How hard is it to pull the strut bearing. Looks like a real PITA! I talked to Greg Meloon at the Chicago boat show and he said I should look at replacing that at my 1100 hours. He also said something about shortening the driveshaft 3/4 of a inch or something like that. They noticed that there is less noise and vibration when you turn. Anybody with experience on this subject??

I'm not sure if I would shorten it 3/4". I shortened mine 1/2" from the orginal length. I would measure the distance between the back of the hub on the prop to the front of the strut and leave about 1/4"-3/8". I thought on the newwer models you didn't need to shorten the shaft on the older models you do, but it should already be about where it need's to be.
The strut bushing are not that hard to change just need to remove the set screws first and then use a hacksaw blade and cut it in to two pieces and it comes right out. You can drive it out but takes a little more effort to get the job done. Some leave it mounted others remove the strut to remove the bushings. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

| This may seem a bit stupid but what are the signs that you need new bushings? I know that the quality of water you run in can make a difference but I haven't replaced my bushings at all. I go under the trailor occasionally and try to wiggle the prop shaft around and that seems pretty solid so I haven't messed with it as yet. |

Backfoot,
That's been my method, if the prop turns by hand without any wobble I figure it's good to go. Chuck ------------- Walk on Water www.coldwater.me http://correctcraftfan.com/diaries/details.asp?ID=775&sort=&pagenum=3&yrstart=1966&yrend=1970 - 69 Ski Nautique |

| Do you have to drop the shaft or can you just unscrew and remove the strut? |

| I removed the strut on mine. I have left it on before on a previous boat. Removing the strut was easier in my opinion. |

If you remove the strut then you can place it in a large vice while you remove the bushing. If you leave it on the boat then you risk causing damage to the boat, not a high risk, but possible. Besides, it is more comfortable to work while standing. ------------- Bill http://www.freewebs.com/billsboatworks - http://www.freewebs.com/billsboatworks www.freewebs.com/billsboatworks 1987 SN Rebuild Project |

if you remove the strut, just be sure to re-align the shaft after you are done, because it will not be aligned unless you are extremely lucky which you won't be. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

the shaft will actually be tight in the bushing when good, when they are wore you'll know, the shaft will be sloppy in the bushing, if it's wore to one side, you better check the alignment, you should check it no matter what,
I have to pull the strut on this one, but i know what your talking about 79, you open up a can of worms ------------- "the things you own will start to own you" |

boy is that the truth. They make some special tools for this task, but I don't think they're necessary http://www.skidim.com/prodinfo.asp?number=SHSBPULLERG - ski dim sells this puller. I like 79's method the best because it doesn't require a bunch of pounding on your strut. M3, yes you have to drop the shaft. I know guys who have used a socket to pound out the old bushing. I save the old one to pound out the next one. Also, I think I read on here a couple years ago that putting the new bushing in the freezer for a while will help it slide right into the strut when replacing. ------------- Mullet Free since 93 http://www.correctcraftfan.com/diaries/details.asp?ID=717&sort=&pagenum=1&yrstart=1991&yrend=1995 - 95 Sport |
