Thanks for all the replies and ideas.
HNut, I especially like the idea about the tin can. May have to give that one a try.
What kind of boat is that?
It looks like a power cat
Yep, a 1971 16ft Power Cat Bull-A-Gator. This one was actually made in Mexico is what he tells me. Belongs to a buddy of mine. He has modified it. Took the stick steer out and turned it into a tiller steer. Then he found another hull that the transom was rotted and cut a piece out of it in the middle. He cut his hull a little aft of the middle and put the piece in it to make it 20ft on the button. Even at 20ft the 60 Etec pushes it about 32mph.
