Jimmy, whilst I can understand the desire for a project
and have the T shirt myself on a previous boat, I would caution you to choose a boat with the engine
in the right place rather than tying to move it from the stern to the middle of a boat. The boat will be balanced, moving engines with the problems of balancing the boat, new stringers and cabin
layout, hmm lots of pain.
Instead chose a boat with the engines in the right place.
A previous project with before and after a simple fuel tank
change, that turned out to be a bit more.
