Volvo Penta Aquamatic Outdrive Stand

When I bought my 40 year old boat, I was terrified because the outdrive was no longer supported by Volvo. Turns out my fears were unfounded because the Aquamatic drives are extremely sturdy, but in the meantime I bought a working spare drive on Ebay for $80.

The spare drive was shipped in 2 pieces and I've been kicking those pieces around the shop for 2 years. I finally decided to make a stand for the drive and put the two halves together so they didn't take up so much space. I marked the drive as a reminder that it would need to be resealed if/when it was put into service.

I Googled Aquamatic stands and found some pictures. I decided the easier/simpler the better and I had some plywood lying around so I decided to use wood. I didn't have specific dimensions in mind for the stand, rather they were dictated by scrap wood I had in the shop.

The initial effort was a simple 90° V of 2 X 4's with plywood ends. I then put the feet on the plywood to make it a little sturdier.

This worked well for totally static storing of the drive, but I knew it would get bumped occasionally, so I added another couple 2 X 4's to wedge the skeg so the drive was kept in an upright position.

She was still a little squirrely in the fore and aft orientation...wanting to lean away from the prop shaft,  so I made a collar for the shaft so it couldn't rock up.

Here's what I ended up with:a

Big Duck's Ground Tackle.

Big Duck carries four anchors.

13# Rocna Fisherman is the main anchor. I wanted an anchor that is light enough to be easily manhandled. These rollbar anchors set very quickly.

22# Claw. This used to be my primary anchor but I found it just a little too heavy, especially since we sometimes anchor 4 or 5 times a day.

Rocna on fold up pulpit (so it doesn't hit the van when trailering) and claw stowed on stanchion.
30# Danforth type. This one came with the boat. I doubt it's ever been in the water?
The anchor 'tube' also holds the dinghy oars and scrub-brush. The smaller tube holds a rolled up mat for puppy potty.
5# folding grapnel. Dinghy anchor or heaving weight for tying a line to shore.
Canvas bag between life ring and freezer, containing grapnel and l00' of 3/8" line.


My line locker has:


150' of 1/2" and 250' of 5/8.
The 1/2" is my primary rode and is always shackled (without chain) to the Rocna on the pulpit.
No Chain On My Rode
The other end of the 1/2" line is shackled to the 5/8" line. The other end of the 5/8" line is readily accessible and can be quickly shackled to the claw. I'm not a fan of using more than one anchor at a time except in high current tidal areas - then it's only Bahamian...never a stern anchor.

All my lines have markers so I can tell how much scope is out and because I have a short brain, the primary end of each line is labeled with the full length.

Remember - if the line is too short, you can splice on another one...but if it's too long - you're out of luck.

Houseboat GTG - St Johns River Nov 2013


Four houseboats attended the November 2013 St Johns River Cruise.
Meander – Jim and Carol (Raisin)
Avitoon – Bud and Michaelle (Penny)
The Ugly Duckling – Jerry and Terry
Big Duck – Jeff & Suz (Merlin)

Jim and Carol live in FL just a short distance from the river.
Bud and Michaelle have a boating business in Georgia.
Jerry and Terry are from Pennsylvania.
Jeff & Suz are from South Carolina.

Previous to the gathering on the St Johns, only Jerry/Terry and Jeff/Suz had met face to face. Otherwise we had only known each other via an Internet group.

As mentioned, the St Johns River is Jim and Carol’s back yard. They know the river like the back of their hand and not only led the great adventure but also narrated on the VHF as they identified sights and wildlife along the way. You’ll find Carols daily blog entries below, giving me a reason not to detail one of my own, but I will fill in some technical info.

You may have read in a previous blog that I had replaced the troublesome ST (Special Trailer) tires on Big Duck’s trailer with LT (Light Truck) tires.

The new LT tires provided a comfort level I never had even with brand new ST tires. This was brought home by the fact that there were failures of ST tires on both the GA and PA trailers on the way down.

You’ll read in the account below, that Big Duck had trouble at the ramp; couldn’t get the engine running once in the water. I just barely had the engine hatch open when Jim and Bud dashed over and were climbing around in the bilge sorting things out. Jim used to race top fuel dragsters and Bud does every aspect of boating work (maintenance/repair/restoration/canvas). I decided I’d just let them have at it.

The first thought was fuel - maybe too much, as we could see raw fuel through the carb on the intake manifold. We tried waiting and ether without results – even pulled and dried the plugs. I didn’t tell the guys that I had just ‘rebuilt’ the carb for the same starting problem.

There was spark, but seemingly weak. Eventually they decided to put the points back in the distributor. A year ago I had installed an aftermarket pointless system by Pertronics, which eliminated timing and dwell adjustments. It had been working very well as far as I could tell and I couldn’t see how removing it would help, but I let them do their thing.

With the points back in, she lit up as soon as I turned the key – and we were on our way. We might have put the old coil back in, but it required a resistor and I didn’t find one in the spare parts locker so we left the Pertronics “Flamethrower” coil in. Boy was it nice to have Big Duck running again.

We ran all day, at about 1,600 RPM, but late in the day I noticed an occasional stumble. We couldn’t reset the timing when we put the points back in – didn’t have a light, so I thought that might be part of the problem and maybe I’d need to tweak the slow speed needle adjustments. Maybe I’d static time her tomorrow morning and then adjust the slow speed mixture.

The next morning she light right up and purred. What a relief. But after half a day of running (again at about 1,600) she started stumbling real bad. When it started to stumble it seemed like I could find an rpm that was good, but now she was loping like crazy. I notified the others that I was dropping the hook to investigate. This time The Ugly Duckling was close, so he rafted for support.

When I got into the engine compartment I noticed the “Flamethrower” coil was way too hot. I would have put the old coil back in, but the old one required a ballast resistor and there were no nuts on the terminals not to mention that one of the terminals on the old coil was stripped. I dug around for nuts that would fit but couldn’t find any – but I did find the ballast resistor.

Jerry, on The Ugly Duckling said, “Hand me that coil.”

He took the coil below and soon came up with a nut to fit the good threads and another nylock nut to fit the stripped side. He even handed me a set of nutdrivers for the installation.

My troubles were over for the rest of the cruise, although I did notice a drop in my mpg, probably due to timing – but at this point with a smooth running mill, I wasn’t about to mess with timing.

 It turned out that our schedule for the cruise almost coincided with a Memorial Service for my Son-In-Law’s grandparents which was being held in FL, about 100 miles from the ramp. We decided that we’d overnight a couple days so we could be in the area for the service. There was a Walmart nearby where we could Wallydock --  the families were ‘motelling’ nearby.

Wishing to ‘freshen’ up before the service, and knowing we might run out of water in Big Ducks fresh water tank, I scouted out possibilities for a fill up. Low and behold, there was a faucet only yards from where we were parked in the Walmart lot. There was a fellow with a Walmart vest on nearby, so I told him I planned to ‘steal’ some water from the faucet near the auto service entrance. He said, “No problem. Help yourself.”

I pulled up next to the faucet and got the hose ready, but before I could get the water going into Big Duck’s tank I got ‘Barney Fifed’ by a security guard who drove up in his cruiser.

“I wouldn’t bother with that hose. You can’t do that!” he exclaimed in a most Barney Fife tone.

I explained I’d just talked to a fellow who said it was OK.

“He’s just a janitor!” Barney exclaimed with a puffed out chest.

Merlin and I chuckled all the way down the street where we found a faucet at a gas station. While we were filling the water tank, a fellow said he made a “U” turn to come back and see Big Duck. We were delighted and welcomed him aboard.


The 500 miles home was uneventful except for a gas stop. When I got out of the van a man approached and said he needed $6 for gas to get home. I had a 20 and a 5 so I gave him the five. No thanks or anything, he stood there looking at me.

I asked, “Yes?”

He said, “I need another dollar.”

I said, “Pardon me?”

He said, “Well, I don’t want to have to ask someone else.”

I almost took the 5 out of his hand.



Here is Carol’s account. (Thank you Carol)

Finally Got Rid Of Those POS ST Tires On My Trailer

When I bought the boat about 4 years ago, the trailer tires were "new". They were new to the trailer maybe, but those 8 X 14.5 ST tires were born over 8 years before they were put on the trailer. We made it the 2,000 miles home from Las Vegas to SC, but I replaced those old tires immediately due to the severe weather checking.

 I bought 4 new DOT rated tires thinking the DOT rating would give me more reliability.

The replacement tires showed signs of wear after about 3,000 miles, and I had plans to tow the boat to Lake Powell which was 2,000 miles from home. I bought 4 new 'highway' tires and stuffed them in the bilge for insurance during the trip to Powell.
New trailer skins in bilge.
 By the time I got to Powell the tread was gone on the DOT tires. I had the new 'highway' skins put on the trailer for the trip home.
Gettin' new skins put on.
 I got roughly 5,000 miles out of those DOT tires.

Well now I'm getting ready for a trip to Florida and I discover a tread separation on my 'highway' tires. This was after about 5,000 miles.
Tread separation and thin tread after only 5,000 miles.
 Further examination showed the tread was completely gone in sections of the other ST tires. This amounts to about $140/tire every 5,000 miles. We surely wouldn't put up with this on our passenger vehicles.

I needed tires that were rated for 3,000#. My boat and trailer came in at just shy of 12,000# but there's 1,200# tongue weight. The tires only need to support a load of a little less than 11,000#. The only non-ST tires in that load range were 16" LT tires, like the tires on my one ton van.
I've got 120,000 miles on the van and am on only the 3rd set of tires. I need the same tires on my boat trailer.
 I learned that there were 16" rims available for my trailer but I had about an inch of clearance from the fender with the 8 X 14.5 tires and the fender was almost touching the boat. If I was going to consider 16" tires that were 2+" bigger in diameter, I would have to do something to the suspension to give me more tire to fender clearance.
Fender can't be raised to accommodate larger diameter tires.
The 'real' tire will need more fender clearance.
 I thought about reversing the shackles or having a longer hanger welded to the frame to give me the clearance I needed. Shorter shackles might have been an option but I already had the shortest shackles available. Then a fellow boating buddy suggested a longer equalizer, and sent me a link to an equalizer that was 4" taller than the one I was using. It was just the ticket.
This is the old equalizer and ST tires. The angle of the equalizer was because I had jacked up one axle.

Old equalizer removed. New equalizer below old one.

The new equalizer installed giving me ~4 more inches of tire to fender clearance.

The new rims were about $50 apiece with free shipping. I placed the order at etrailer (https://www.etrailer.com/) on Sunday and the rims arrived on Wednesday. The equalizers were about $25 for two from etrailer and even though I ordered them after the rims had shipped I got the equalizers with the rims because I emailed the folks at etrailer and asked if they could combine the shipments - they couldn't but expedited the equalizers.. The tires from Walmart came in at less than $500 for 4 brand new "E" rated tires mounted on my new 16" trailer rims - these are the exact same tire I use on the van. I also sprung for 4 new shackle bolts at about $20 total. And now I have REAL tires on my boat trailer.
New REAL tires on my boat trailer - SWEET!
Both of these tires are brand new. The one on the top is an ST tire with pasty shallow tread. The bottom tire is the real thing.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Update as of 4-2015
I've been challenged many times about using non-ST tires on a trailer, but have yet to hear of anyone that was sorry they they went to passenger or LT tires on their trailer.

My Take On Torque

I dropped out of college 'cause I didn't have the brainpower. That may explain why I have so much trouble understanding why torque numbers have such a big place in the advertising of personal vehicles. Semi rigs don't boast about torque, nor do large farm tractors - all they care about is horsepower. To further complicate matters, one can have torque without work and one can have work without torque.

In days past, I guess it was meaningful to know your diesel pickup had exceptional low end torque. This meant you could let the clutch out at idle and pull your boat up the ramp. With a similar gasoline powered pickup, you'd have to rev the engine to get her up in the torque curve and feather the clutch or the motor would lug and die. But things are different today because we have sturdy automatic transmissions which take the guesswork our of how many RPM's we'll need to get the work done and there's no clutch to feather, so what do I really care about where/how torque comes into play?

There's an article at How Stuff Works that says a gas motor can match the torque of a similar horsepower diesel motor by the use of gearing. To me, this suggests that torque is more a product of mechanics than the ultimate ability to get work done.

So here's how it makes sense to me:
Horsepower does the work. If you want to do more work or faster work you'll need more horsepower.

Torque is the potential ability to accelerate. Where the big torque numbers show up on the RPM curve, that's where you have the ability to take on the most work. In the case of the diesel, it's at a low RPM. In the case of a gas motor, it's near the top of the rpm range. But with the proper gearing either will produce the same amount of torque, just at different RPM's. If you want to have more torque without gearing you add horsepower.

Let's say our car is jet powered - no torque involved at all. How do I make it go faster? Yup, by increasing horsepower.


So like I said, it appears to me that if you want to do more work or do it faster, you add horses.

Lake Kerr September 2013




Folks on the Houseboat Forum were excited when someone proposed a gathering in Florida in November. There was talk of exploring many of the Chain of Lakes and exciting shore side activities, but when it came to commitments, there were only two boats -- Big Duck and Ugly Duckling, both ’72 28’ Land N Sea houseboats.

Jerry and Terry with Ugly Duckling would need to tow almost 1,000 miles to get to Lake Harris from Pennsylvania. Suzy and I would need to tow Big Duck over 500 miles to get there. My brother-in-law Doug said he and his wife Elaine would like to join us, a 1,200-mile tow for him from Chicago. Since it was just the three of us, we decided to get together sooner and closer. We looked for lakes somewhere between PA and SC and decided go give Lake Kerr, on the NC/VA boarder just off I85, a try. I posted our intentions along with an invite, but the only one on the board that replied was Lee. He’d like to stop by even though his boat wasn’t yet water ready.

Ugly Duckling had been recently purchased/retrieved from California and had not yet been in the water after years of storage. Jerry said her systems checked out OK and he believed she would be ready in time. He’d be there "if she floated and would move under her own power". I told Jerry that Doug and I would be there either way and he should just come if/when he could.

Doug, Elaine and their Parker 2120 arrived at our place in Spartanburg on Wednesday. We’d caravan up to the lake to arrive sometime on Saturday 9/21. We’d spend the night aboard in the parking lot in case Ugly Duckling was late arriving. It’s a rather pleasant drive for us – 5 miles to I85 from the house and it’s about 5 miles off I85 to the Flemingtown ramp at the other end of the 250 drive. Before we left, we got word from Jerry that he wouldn’t make it on Saturday…it could be Sunday or more likely Monday, but that didn’t deter us from our plan of a Saturday arrival at the ramp.
Rest Area stop to check tires and hubs.

On our way up, I got a text from Lee. He and his wife would like to meet us at the ramp to have a look at Big Duck. They would also like to talk to us because we had been doing the kind of boating that they planned to do now that Lee had retired. Lee is restoring a Yukon Delta houseboat and hopes to have it ready for a 2014 gathering.


Doug/Elaine and Suzy/I planned to sleep aboard our boats in the Flemingtown lot on Saturday night in case anyone else showed up Saturday and wanted a tour. As it turned out, Lee and his wife caught up with us on I85 for the last 10 miles to the ramp and we had a nice meeting in the lot. I was encouraged that we could be an inspiration for Lee to get his boat finished. 
Lee and his charming wife.

From the looks of the beautifully detailed work Lee has done so far, it’s hard for me to imagine how he can get it finished in only a year…but you never know. 

We did stay in the lot overnight.


Mokee Dugway and Big Duck made day trips on Sunday, Monday and Tuesday, tying up at a ramp dock each night in hopes of finding Jerry there when we arrived or when we woke up. Cell coverage on the lake wasn’t reliable and we didn’t know when they would arrive.  Normally we’d anchor out but we were anxious to meet up with Jerry and didn’t want to have to tie up our boat(s) in the dark. There was no activity at any of the 6 ramps during our stay there, and the dock we used didn’t even have a ramp. Jerry, Terry and Ugly Duckling finally arrived late Tuesday night. 
Ugly Duckling in the morning.


I can’t remenber a more pleasant time aboard than we had on Kerr. The mornings were just a tad crisp, the days were very comfortable with blue skies and the nights were great sleeping. To top it off there were no bugs, and I mean none – well except for an occasional stinkbug. 
I love you Merlin. I love you Suzy.

Pure comfort - get me a beer will ya?

Am I doing this right?
This is the life.





Hey Cap' - you left the fenders out!

We did have a little bit of excitement when Jerry came on the VHF to say he was dead in the water. His propeller shear pin let loose so his prop wouldn’t turn even though the engine was running fine. I towed him to the beach and we hunted for something that could be used as a shear pin. This was far from an emergency because Doug’s Parker can go 40 mph and he would have gladly run us back to the ramp for a shore run for parts...there was really no urgency.

I had made a couple tools on the lathe for removing/replacing my propeller and one of them was almost the right size to be used for a shear pin…we could cut it to the right length but the diameter was a few thousandths too big to fit in the shear pin holes. Jerry asked if I had a file and a drill – I had both. We chucked the pin in the drill and ran the file back and forth against it as we spun the pin in the drill. We turned down one end, then the other for an exact fit.

We spent 6 nights aboard and put over 100 miles on the boats with one run up to Clarksville exploring the dam, 

Mokee Dugway at the dam
beaches and ramps along the way. The Virginia end of the lake has many, many boating and swimming facilities – more than I’ve seen anywhere else on the water. We especially enjoyed rafting overnight in the waters of Occoneechee State Park. We tied Big Duck up to the ramp/dock there the next morning and found the grounds immaculate.


Because the trip was so inspiringly perfect, everyone, Jerry, Terry, Doug, Elaine, Suzy, Jeff and Merlin are anxious to get out on the water again soon.
