I am finishing up a Mojo 40 and looking for the final details now (first build in over 12 years, feels GREAT to create again ). Power is a ST45 and I want to use an aluminum prop nut instead of a spinner. What brands and sizes are people using for these? I was looking at the Dubro 1-1/4" ones, they are fairly cheap and easily available. What other choices are out there?

Thanks,
Mark

I use the Higley acorn shaped ones with hex sides and matching nuts on all my 4 strokes. They're light and easy to tighten with a crescent wrench:

These are the lock nuts I was talking about for 4 strokes but you probably won't need it for your ST:
