i recently traded a 25 hp merc for a 18 hp honda on a godevil frame long tail. Go devil does not make long tails with 18 hp honda. I was looking at the go devil props; i think a 9X4 would do the job. i was just wondering what other manufaturers makes props for mudmotors that have the same specs as go devil. I had a bad experience with a prop i bought off of ebay but the guy did give me a refund it was for an older motor i had.

Mud Buddy, Beavertail, and a couple others I think. Dont know if they all use the same brand prop or if they actually make their own. For an 18 hp, the same prop for a 16 briggs should be what that motor would use. I think the 9x4 would be right.
