Honestly, I don't think its worth putting the big block in the inboard. My boat is no faster than the other inboards (avg 20 -22 knot cruise) that have 350's in them. The 454 is a very fuel inefficient motor designed back in times when gas was cheap. When I go to repower I will most likely use a new vortec 5.7.

The inboards are limited to at most a 17" prop and just are not that fast. If you want to go fast you need to go yanmar as the diesel torque can push the boat up to the 30 knot cruise range.

I would not go messing around modifiyng the inboard tunnel to work with a surface drive. Inboard seacrafts are in high demand. The last inboard listed here at CSC sold in a day or two. You could easily sell the hull for a nice price and purchase a boat originally setup for an I/O.

this is good advice !



this gentleman has it right !
