transom shot

[jonesg]

Hi, I have a 73 Chrysler 20' center console project boat.
The plan was to seacast the transom but theres more damage than expected. The inside transom wall is gonzo (below the splashwell.)
We've already removed most the of the transom wood, hull is glass.

I cut the splashwell off and everything is soft so I'm gonna gut all that out. 4 feet further fwd the wood is good.

My plan, please tell me if this is workable, is to remove the console, cut the glass deck off and replace/rebuild the damaged /wet wood.
I already ordered the seacast so I may as well use it now.

We want to get this done before winter, feasible?

Eh Jones,

If you've had problems with wood, why go back to it ? I would consider making a webbed fiberglass thansom that would never give problems again. It's going to be more work but you have to do it only once. Save a bit of weight there too.

I agree, thats why I ordered seacast resin to replace the plywood transom,

but theres a substantial amount of substructure beneath the splashwell area that is wood and at this point I can't afford any more exotic material. The original wood lasted over 30 yrs.

The seacast poly resin has a 6 month bucket life, by next March it will be out of date so I need to try and get at least the transom poured before winter, the rest can wait if need be.

Jonesg,
This is a little late, but hopefully, you were able to pour the transom. The Seacast worked well for me. There was another post I saw today where they made a wooden form and filled with seacast. Turned out nice.

The other structures, you might want to use wood, glass and epoxy. Wood is strong stuff and works well. The guys here on this site are VERY good, and can help you do anything you need, if you give them good photos to look at. I hope it works well for you.

I got it poured with seacast this spring, just got around to mounting the 150hp yesterday actually.
New stringers and bilge paint, I also re-cored the deck liner with home brewed seacast.

photo is heatlamps on the seacast in February, keep it warm!

I forgot to insert nuts and bolts to hold the transom thickness and now its 1/2 inch thicker, had to buy $30 worth of longer stainless bolts to reach thru.

Looking back it was an enjoyable little project, whilst the deck was off I replaced the 50 gal tank and replumbed with all new lines, new bilge pumps etc.

If you can get hold of DMA you can make your own seacast using BPO as the slow catalyst, I couldn't source it but its out there...someplace.
I think it stands for dimethyl acetate?
