[QUOTE="Johny25, post: 328461, member: 7791"] I show 4000 as being the RPM specs also so that is where the 15hp should be at. The 18hp didn't come out until 1957 I believe and it was a different motor and displacement so its likely they didn't have same prop size. Maybe Pappy will see this post and chime in, he is good with these vintage beauty's [/QUOTE]
