20hp is great, tops out at 29mph. Yamaha has a new 25hp out that weighs same as a 20hp. That would be my choice.

Fatal Error?
So I used the nails 6 inches on center, for the second lamination of the sheer, but as I read after the fact in the boat building with plywood book that these should be nailed from the inside. Makes sense. I have no idea how I am going to fair this now.
Any suggestions
?

Most tools that folks commonly use for fairing will go right through those SB nails.

Beltsander. Planes are out unless you want to become an expert in sharpening. :D

Angle grinder with flapper disc. I sanded through a few nails in my gussets while fairing with no issues.

Seconded. I couldn't get a satisfactory clamping job on the first laminations of my sheer, so I screwed it down between the laminations, the angle grinder ate through the #10 screws just as quick as the wood.

Out of curiosity though I'm curious how many recommend the screws/nails between laminations at all? I only put screws at the frame junctions, and only after fairing in most cases. Everything else is epoxy.

It probably depends on the boat. My plans call for screws every 6" along the sheer lamination in addition to at the frames. I was concerned about cracking at the screw hole and plane damage during faring so I waited until I had a planking layer on add the screws.

My sheer laminations don't have any fasteners. I just used a "boatload" of clamps.

Poxygrip and clamps. Screws and nails just get in the way during fairing. Only one screw at each frame.

The way I look at, I put the screws in the laminations when the planking goes on and running into an existing screw while attaching the planking sucks!
