I was thinking the bolts too...dont use a torch you'll catch the boat on fire, I hope there is a better reason for taking it apart then to clean it... good time to check the alignment ------------- "the things you own will start to own you" |

I think it looks pretty clean like it is - but I live on the salt water so what do I know about clean...
Here's a dangerous tip, and if you get hurt I am not the one who suggested this - it is some stranger using my computer: Run the boat at idle in gear and hold a wire brush on the coupling. Be sure to tie your hair back first (if you have long hair). If you are short on time run the boat up to 5000RPMs when doing this.

we'll tell the legal team, Jim told him to do it,
we were just talking about a guy 2 days ago who got his hair caught in a lathe and it scalped him. actually i would do the same ------------- "the things you own will start to own you" |

Seen woise...
Try a rubber deadblow hammer else Remove the bolts, lower the front engine mounts one turn exactly, and turn the prop, put the engine back. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

Nice Jim! Actually the purpose was to check the alignment. I had a decent amount of vibration last year. I know the prop was part of the problem - that is now fixed. I haven't been on the water yet this year so I'm not sure that cleared it up. Thanks for the tips. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1840" rel="nofollow - 1989 Ski Nautique |

I hope everyone knows I was kidding. It's my perverted form of humor. Please do not get in there with a wire brush while that shaft is spinning. You could lose a finger or worse... ------------- Happy owner of a '66 and a '68 Mustang |

When I pull that off the first time I always index the shaft on the coupler and face the coupler on the lathe. Unless you know the coupler and the shaft are perfect there is no use trying to line it up. Use lots of antiseize when you put it back together.

I have not tried this...but...what about loosening the bolts, launch the boat and hit reverse hard? the torque and pull of the prop should break it loose...maybe.... ------------- |

I'd be afraid the prop would continue back right into the rudder, unless the collar is set properly on the shaft. Either way, with all due respect, I'd have to say this is probably a pretty bad idea. ------------- 2000 SN GT40 w/99 Graphics/Gel 2016 SN 200 OB 5.3L DI https://forum.fifteenoff.com |

Well, I said loosen the bolts, not remove them. The bolts still being in place would prevent the prop from hitting the rudder. ------------- |
