    Transom replacement.

    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...

    Transom replacement.

    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...

    Transom replacement.

    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...

    Transom replacement.

    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...

    Transom replacement.

    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.

    Transom replacement.

    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...

    Transom replacement.

    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.

    Transom replacement.

    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.

    Transom replacement.

    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...

    Transom replacement.

    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 )...

    Extending trim switch to engine cowel.

    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...

    Extending trim switch to engine cowel.

    This looks like it should work. If I may ask, how did you tap into the wiring? I understand the hot, blue, and green situation. I have a Force Service Manual that explains how the tilt/trim is wired. Just not sure where to tap into?

    Extending trim switch to engine cowel.

    There is already a switch at the helm already. I have to reach with a broom stick to hit the switch. No switch on the cowl. I want to add one near there.

    Extending trim switch to engine cowel.

    '88 Force 85hp. I am tired of having to use a stick to lower/raise the engine from outside the boat during launching/loading. I would like to add another tilt/trim switch near the stern. I am no electrician but me thinks I could run in parallel and simply add another switch or would it have to...

    85hp 3 cylinder Force carburetor throttle plates.

    Ok thank you. I understand that now. They seem to be opening correctly now.

    85hp 3 cylinder Force carburetor throttle plates.

    Its an actual service manual. They just dont go into details sometimes if you cant get something right. In this case I think I just had to redo the tiebar a couple times to get the plates moving equally.
