Finally, finally getting back to this work... Many distractions but I did move forward with the engine build. It is in the assembly stage. So, I plan to use West Systems epoxy to bond the plywood to the hull.
Here goes the additional questions:
1) Do I need to put chop mat on the plywood first and then use peanut butter between the plywood and hull or just seal the plywood with resin and then peanut butter when putting it in place?
2) Since I have that big OMC hole to fill in the hull, is it best to leave that area free of epoxy and use polyester resin to layer out the hole for gel coat?
3) This is a large transom area so concerned with setting time since it will take a while to coat the transom wood and hull before setting the wood in place. I have both fast and slow hardener, will be likely putting it in place as soon as the weather hits 70 degrees (SW Washington State location). Thoughts on hardener?
I am trying to convince myself that I can do this and end up with a solid bond that I don't have to worry about out on the water. I see the West Systems uses a "calibrated" dispensing system to get the epoxy to hardener ratios correct so I guess I don't need to worry to much about it not setting up due to screwing up the hardener amount. So need to satisfy myself that I have enough time to get the peanut butter in place, the new transom in place, and then clamping done before it all sets up.
By the way, I do now have the Mercruiser Keyhole metal drill template once I get to that point.
