I'm going to start installing the outboard motor on the back of my car tomorrow. Is there a rule as to propeller diameter?

As long as each blade is within 1/2 " of each other, you are good to go!!! LOL
Remember, too much pitch is like running 5.80's!!!!!

Propeller diameter is is determined by number of blades on said device. Total driving surface of propeller will not exceed 50 sq in. So more blades, less diameter. Remember, utilization of "sail" panels greatly reduces curvature of blades, also only approved non-metal blades allowed. :cool:
