UPDATE: Now onto gelcoat. Color matching is a huge pain for this. I wetsanded the above area. Having a tough time getting a match. Im using white base and added little yellow black and brown heavy on the black. The lighting in my garage makes it difficult to tell. Also I decided to ROLL on the...
Thanks Mike, very helpful write up.
Just to update this post, Im at the point of getting ready to attach the outer skin (fiberglass). Glueing the transom wood was a success using thickened epoxy 2:1. I was surprised how much cabosil it needed to keep from sliding down.
Anyways, I want to use...
Yes since this is the first time I am doing this type of repair it would be helpful. Im taking my time at this point and doing as much research as possible. so far everything is straightforward.
But Im stuck at the part of adding glass to the bevelled seams after the glue up using the old skin...
I am going to roll the gel coat on with some type of fabric roller. Maybe a foam one? I have a hvlp gun but i dont think its the right tool to spray gelcoat so im just going to roll.
Do 3-5 coats i suppose until im happy with it. Ill use unwaxed for these coats and of course waxed for final...
I agree. That was what I had in mind. Just not sure if it would work or not. I think if I use enough epoxy PB it should stick and never come off. Do I need to lay down any glass on the outside of the wood before I glue the skin?? I assume I would have to use something like 1708 if using epoxy.
OK. I understand the styrene issue with epoxy. What I plan on doing is using epoxy PB to glue the wood and outer skin on. When I go to tab in the seam on the outer skin I am going to use isopthalic polyester resin. I suppose I can use CSM for that but I think I will use biax 1708 to tab in the...
Ok thanks. I think that is a standard weight in the industry for these small glass boats. Ive made the decision to go with epoxy for this repair. And then wait for it to full cure for a week. Then grind with very low grit and apply my gelcoat. It should work based on the research im doing.
This was my inital idea after researching.
On the tabbing i assume polyester (isopthalic) will be fine if i bevel the edge all the way down. Just not sure what type and weight glass to use. Ive been reading people use vinylester as well.
I do have access to the inside although its pretty tight. The other side of the splash well there are boards I can cut and then just tab back in. Shouldnt be a huge job to do that. That should give me enough room to crawl in there and get some glass and gelcoat.
I definitely thought about...
Well, I finally decided to tear into this thing. It is a fiberglass boat from late 80s and about 90% of the transom wood was soft and rotten. I did not notice any cracks or bowing.
I removed the outboard to fix the transom cap (was in really bad shape and I wanted to add a piece of aluminum )...
How would you actually tap into these wires? Disconnect from relay. Remove crimp. Use a wire nut? Then crimp on another connector to slide into the relay?
Yes... I ran the hot from the circuit breaker that the other "red" hots from the trim motor connect to. I tapped into the blue/white and...
