  • Cool vid....I have a question.i just bought a mustang with 4 stroke os 120 with spiiner and when i was trying to breakin the engine i seemed to have stripped the back part of the spinner backplate now theres not much for the engine to grab onto.Whats the fix for this? should i tightn the nut extra harder to keep the prop from moving?

  • I assume you have a good quality spinner... Since the motor shaft is hardend steel, I crank the nut as tight as I can with a standard prop wrench. I just about crush wooden props. Yes! tighten it extra hard.
