Re: Aluminum transom reinforcement

Since the origional plywood has only been replaced twice since 1965 construction, last time in 1992, this forum has convinced me that I would be fixing something that is not broken if I went through with a welded aluminum addition. I actually have been working on a glue-up of multiple pieces of 8 la...

Re: Aluminum transom reinforcement

This boat is a Lone Star 17' made from .090 aluminum This boat has a sizable trough in front of the transom that I thought was a splash guard and a battery and steering cable holder. I have no intention of modifing it since it is an integral part of the hull. I thought I would just replace the curre...

Aluminum transom reinforcement

I have had an old rivited 17 footer with a 6' beam and 36" max freeboard for some time with a rotted transom. Instead of replacing the rotted plywood I have decided to spend the money and replace the plywood with a heliarced panel. This is an outboard powered by an old 1978 3 cylinder evinrude 70 HP...

radiator cooling issues

I would think the thin copper or aluminum radiator to be short lived in a marine situation. Keel cooling solves all the heat exchanger issues. There have to be comprimises but off the top of my head I can not see any serious issues. Sandy at sandyscb.com built a steel-hull 42' BR sail boat and just ...

Source of used aluminum sheetmetal

Has anyone used the aluminum from a scrap aluminum stepvan for a boat?
Appears to be a good source for .090 stock if it is good alloy.

broken-bolts

You have come up with a solution that I have not tried!! I weld with a stick, but have always wanted to do tig/mig so I can weld aluminum and sheetmetal. I will have problems consistantly placing a bead on a 1/4" bolt shank. Will require much practice and a steady hand. If you say it works I am game...

Any techniques on removing seized bolts????

I am attempting to get several old outboards, Evinrude 70 (1974) and Johnson 10 (1960), back into shape. Attempting to tear one down is really a problem. Using an impact wrench to try to headoff twisting off the bolts results in almost every one of the .25" bolts twisting off. Heating the bolts red ...

Styorfoam sp is what the previous owner used. They accidently spilled 6 gal of fuel in the bilge and melted almost all of it. I have replaced all the flooring and seats with new ply and now need to replace the styro. THe company that specialized in floatation fom is about 30 miles from me so I can d...

Foam flotation

I need floatation for my old aluminum boat. Initially it was cut block foam but a fuel spill melted all that back to plastic. I don't like the idea of foam-in-place for the aluminum hull because trapped moisture will become a corrosion problem. Are any of the foam insulation products from dow chemic...

I am probably out of line here but:
I think seats should have cushions that can easily be removed and placed out of the weather that they will stay nice.
The first thing to go bad in an open boat are the seats.

Old Johnson 10HP QD-21

Got an old 10 HP Johnson today, complete except rewind starter is gone. As per a parts catalog I found it is a 1960 model, later years went to 9.9 HP. Even has mostly paint left. I was suprised at how old it is. Turns over and has compression. Xmission shifts. Prop is still usable Should I attempt a...

Appreciate the responses!! No carpet to be added to boat. That's probably what caused the demise of the previous floor in JUST 16 years. Actually I looked at several aluminum hulled boats and most of them with carpeted floors had some rot at around 6-8 years of normal use. I already painted the piec...

Cheap floors

I purchased bd .75" exterier ply at the home center. They no longer carry AC. I selected sheets with no repaired voids on the b surfa...

I am not big on welding thin aluminum or steel for that matter. I have welded steel for years and can handle aluminum with the proper equipment and some practice. The project will have to be large enough to justify the cost of the equipment for me to personally weld it. This old boat was built in 19...
