Where did you have it done? And how bad did you get raped? I have had 2 bad experiences with glass guys...which ended up costing big $

he made right, and offered to fix but i want to do it myself.

damnit now you have me thinking i might be able to fix it lol. I just wanna cut the ****ing hole and drop the motor in!!

Cut the hole and see how good the lamination is. Wherever there are bolt holes you can drill them and thru bolt them to such the outer skin in and make a better bond.

I just came from one of Canadas best boat builders and we were discussing this. I'm not an expert but I'll try and repeat what he said. Based on your photos you need to strip off the gel on the floor and the stringers a little way forward from the transom because you cant bond to gel. Then sand/scrape all wood off the transom until you only have the outer shell. Then install new glass using a special resin that will bond to old glass. (I forget the name) then install your sealed plywood (baltic birch) then start tabbing it in to the stringers and remaining transom. no need to make putty just buy the pre mix and only use it to fill gaps. The keys are don't go over old gel, use the right resin to bond to old glass with new glass then install your wood to that glass and tie it in to the bottom stringers. hope this helps

Im using vinylester resin, it really just didnt get sucked into the fiberglass enough i think, plus maybe the mat was a little too thin for a somewhat uneven/large surface

Where can you get corebond at?

Glassdave might sell you some he is right across the border in oh

I like to make a thick resin using cabosil on top a layer of mat using a notch trowel spread onto wet mat then bond your core.For the edges fill with resin,cabosil,and chopped strand curving the edges for a good radius then use your biaxial, just my 2 cents
