I was wondering whats the recommended heat range the plugs should be? Also is there a standard pitch prop for this motor?

QL-82c Champion plugs.
If oil injection is still hooked up I suggest you disconnect it and run 50:1!!!!!!!!!!!!!!!!!!!
Props fit the boat, not the motor if always on the same boat tach it out to besure motor is reving in the recommended range.
