Project questions

[CBradC]

I will try no to ramble but I am slightly overwhelmed by this potential project and am seeking advice. I have a chance to pick up a mid 70's Seacraft 23 cc with a straight inboard. The boat is rough but seems solid. The engine , transmission and all associated components are in place but have been submerged in freshwater for along time and I believe are beyond use. Is it possible / practical to add a bracket and an outboatd to this hull or would it be better to restore it as an inboard. It has a tunnel in the hulls bottom to accomodate the shaft and prop so I have no idea if a bracket could work or not. Any ideas on the costs to replace everything from the engine to the prop? Thanks for your opinions , standing by!
