'88 230 restoration (rotten transom)

Thanks, I updated all the pics in this thread from the first page on so the majority of the work can be seen right here.

Here is another pic of the gantry I made to pull the motor as well.

The upper beam is a 4x4 with two 2x6 runners bracing it on both sides. With the full weight of a completely dressed Fresh Water Cooled 454 there was virtually no bending in the cross beam. It was also very stable in all directions.

Pulling the motor to start the process.
 
I know this is an old thread but what did you use to layup the Coosa board and the other fiberglass? Was it epoxy or polyester? How hard was the Coosa board to work with? Does it need wetting out with resin or is it already done at the factory?
 
Looks like all my picture links have been stripped from the thread.
:huh:

Coosa is very easy to work with, it is basically foam with fiberglass reinforcement, so it cuts and sands easily. I used an epoxy bonding resin to adhere it to the existing transom glass. I could dig up the brand name again in a PM if you need it.

Think of working with Coosa as working with plywood, just easier, lighter, and stronger. It's only weakness is against chafing/rubbing since it is foam based, but if it is embedded in fiberglass that is a non issue. It even is nice cutting in that it does not create fumes or a lot of dust as the cuttings generally are like tiny foam balls. You do need to where gloves and protect against fiberglass threads though.
 
Excellant work. And thanks for sharing all the pics.
I really like the gantry. :smt038
 
If you could PM me a source for the Coosa board that would be great. I'm recoring my swim platform on my 89 300 and I'd like to get some experience with this composite in case I ever have to do a transom or stringers as you did. I realize Coosa is overkill for a swimplatform, but I like the no rot properties and the lighter weight aspect of it. I'm also considering Nidacore and Seacast, a pourable composite, although it is heavier than plywood. I'd like to drop some weight if I could, that platform is heavy enough as it is (water logged). Thanks for the great pics in your post, you can be very proud of your workmanship, it truely looks superior to factory.
 
hi,
I have a question on the alpha drive. I had mine redone last year. never had a drive before. I noticed the drive would vibrate if I turned it left or right.I does it with the drive down or up. The repair guy says its ok. Wondered what you thought

That is typically the sound when ujoints fail on the driveshaft.

I was wondering if you could advise if when you did the resto did you remove the deck or did you work from under the deck thanks Roy
