I have a 19' 78' SN 351w Commander/ Velvet Drive/ 1" shaft. It needs a new prop and I am considering replacing the (original?) 1279 Federal NT-BKAL CUP 13RH13 #HH49012 ( 3 blade) prop with the Acme #540 or another you guys might suggest.
I saw Keith's article and wondered if anyone might know how much clearance is enough for the 540 to fit without having it recut etc.? I have 5/8" between the blade and the hull now. Also I think I need new bushings and wondered how they get replaced. Any special tools or other reccomendations or tricks? Many Thnks, NM ------------- Nautique Mike |

Mike...I just got a 540 (for a 72 SN), but have not run it yet...still waiting for my seats to get finished
Anyway...it is 13 inch diameter same as the old one...so fit is not a prob. Let you know how it performs. 5/8's??? that is really close...I have at least an inch. ------------- stang Face plants are not that funny when it's you face! http://www.correctcraftfan.com/diaries/images/3720/photo1.jpg" rel="nofollow - The Super Air |

I like the 540, huge difference, direct bolt on. Bushings? Dunno, never changed them. When I find another $300, I would like to try out an OJ 3 blade legend also. ------------- 1980 Ski Nautique Ithaca NY http://my.break.com/media/view.aspx?ContentID=326707 - My Boat |

maybe its NI-BRAL like most others. Nickle, Brass, Aluminum. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

My new 4 blade OJ prop is outstanding. Amazing low and mid-range acceleration. I find that my boat doesn't vibrate as much. The wake is smoother at 30 MPH. I'm using in on my '86. Big difference!
