I have a 72 which is undergoing a keel up restoration but I haven't worked on it for awhile due to working on my new house. Its upside down on...
Wow I think that is the first Hydrodyne I drove! I was the pickup boat driver for 4 years in the mid 70's
Your boat looks identical to my '72. My boat does not have a HIN or a capacity plate. This should at least help you narrow down the years.
Balsa is the wood of choice because it is light and porus. Oak is heavy and non-porus. Pine is somewhere in between but cheap. I used core...
No power yet but plan on twin 150's
I am in the process of doing exactly what you are planning on with the coosa. Check out my thread under restorations "1972 keel up restoration"....
Good point Kevin. I have very little experience with IO's.
Menards will take the wood back. Vertical seams would be the worst thing you could do. Horizontal seams would be ok if staggered and the lengths...
Not enough. 3 layers minimum. Factory transoms were 2". Make sure the layers span the entire width and stagger the horizontal seams.
How many layers of plywood are you planning on using in the transom? Doing it in pieces and not one solid layer upon layer will be significantly...
2 x 12's as clamps is a great idea. Use resin and cloth between layers
I don't understand what you plan to do with the 2 x 12's. Are you adding additional knees? Laminated layers of plywood would be better.
it's tough to do it right without removing the deck/top. But I think it is possible. Get all the wood out from the transom. If possible stand...
A single 3/4" engrain balsa will do it. The stringers will give more support. Mine is bullet proof.
Check out my thread "1972 Keel Up Restoration". I have already done the core and have lots of pics that should help.
