Converting Car Engines to Marine

Marty Davis said:

What is the process of converting a car engine to marine? Especially, how do you convert the car crank to a flywheel and cable collet setup? I have never use a car engine and wonder how difficult it is to accomplish.
I probably would not use one, since I like the rear rotor engines. They make for a much neater installation in a boat. I don't think that any car engine that I have seen is a rear rotor configuration.

Marty,

Get a car motor with the SG crank.

Take a Dremel cut-off wheel and remove the pilot shaft leaving the 1/4-28 threaded stub.

Chuck up the flywheel and counterbore the face of the flywheel about .100-.125" deep so the hex of the collet will recess into the flywheel face.

This will leave enough of the hex outside the flywheel face to get a wrench on to tighten up the collet .

If you want I could take a photo and send it to you if you need it for clarification.

Thanks, I understand what you are saying. I just didn't think that there was enough thread on the car crank to secure the coupler. Guess there is....

Are there ANY rear rotor car engines, or all the front exhaust style?
