A quick update.
1. The transom wood is rough cut to shape. I'll need to plane it or belt sand it to fit, and then I'll drill holes, and then seal those and the edges. I'm still not sure the approach I want to take to fill in the outdrive hole. I'm worried about welding in a patch just to fit the hole. I'm thinking I'll make an aluminum sheet on the back of the outboard bracket that I can seal with 3M 5200 and bolt on with the bracket. I'm planning on making knee braces to tie into the motor mounts and stringers.
2. It's been cold again in Michigan and since the boats outside I haven't felt like working on it - mainly because its uncovered. So I'm rigging up a PVC pipe canopy of sorts I'm going to cover with clear plastic. At least this will keep out the snow so I don't have to clean up the inside every time I want to work.
It's bigger than it needs to be in these pictures. I want it to fit inside the boat while I'm working.
Yes, it still needs a few pieces to make it stable, but I wanted to put a simple frame together as proof of concept. I think its going to work fine.
3. I'm working on getting the Yamaha's off of the Whaler - but again its been cold and I haven't felt to motivated.
Another picture of the Whaler - just for fun
