So when I drop these shafts off at the machine shop today, what is the max runout that I'm having them look for along the length of the shaft. I know I've seen the .003 number in reference to the coupler, but I've also seen it in posts instructing people to check forward/aft of the strut with an indicator...... looking for .003" or less.

Believe that is correct... .003" max for both shaft runout and coupler face alignment. Pete will confirm.

Chris,
The runout at any point in the shaft should not exceed the .003". They should also check aft of the strut on the prop taper since this is a spot that is a frequent bend. The shaft is supported forward at the trans end and aft were the strut normally is and then they indicate the prop taper. Yes, Duane confused things talking about alignment with the .003 between the coupling faces when we've been talking shaft straightness! |

If you have a shaft that is out, say .0045" and you straighten it back to say .0015", is there any negatives such as weakening, assuming heat was not used in the process?

.003 would certainly be within tolerance. Have them "chart" where they are out and how much. That will give you a good idea of whether to use them or not. Why not purchase a tapered coupling and have them machine the shaft for it?? Then you will have a double taper shaft which is much easier to service now and in the future. They will need a reference dimension to work to. Meaning end of shaft at the prop end to the face of the press on coupling. That way the new coupling will measure the same as the old when assembled. Or go pay a ton of $$ for a new ARE shaft and have basically the same thing. Your choice of course. Other opinions will surely differ. Duane |

When they measure runout, I would have them use v blocks at coupler end & also at strut area. (as opposed to end centers). That way they are duplicating the boat geometry.
Several members have had success straightening a shaft. |

Duane I will absolutely look into getting the shaft converted into a taper if it's still good. First I have to find out if it's still usable.
I got the shaft removed today. I went with Joel's method of using a small impact drill to carry the load. I can't even imagine doing that job without it. Even with power tools it took me 3 hours (with a lot of that removing striped bolts). *******word of advice to anyone thinking of attempting this. Get good bolts and nuts to create the press. I used regular zinc hardware from Home Depot because it was what was available to me with short notice. If I had to do it again I would go get much more sturdy hardware from a proper source and not worry about stripping and cutting bolts. Interesting side note, when the shaft came out of the 176 it measured 43 inches. When I put it side-by-side with the shaft from the Promo, it was considerably shorter. The Promo measured 50 inches. |

Chris I dropped both shafts off at the machine shop today. I spoke with the guy that took care of my manifolds back from when I bought the boat. He showed me the V-blocks and his setup. He pointed out that both shafts need to be cleaned up before they can be measured due to the corrosion and build up left over from the couplers.
This little project could cost me $200 or $900........so fingers crossed. |

Chris, We (HD) carry grade 8 fine thread bolts and nuts. We also have never seize. You must not have looked had enough or not asked an associate! Don't blame HD for you're not getting the hardware from a "good source". |

Pete you probably work at a good one. My neighborhood HD is on the fringe of a few different neighborhoods. The isles look like they got hit by a tornado and you're hard pressed to find an "associate" that speaks passable English.
However, you're correct in the assumption that i didn't look very hard. |

Hahah. If I went that route it would be $900+ for sure. I'm doing this for 2 boats. |

Wow, I won't be hitting any logs anytime soon. Just looked the current price up
Looked up my receipt from almost 2 years ago, figured it was about same price. Paid $375 plus $29 for shipping. That might sway my decision too |

While waiting for the shaft to return, what is the favorite place to order cutlas bearings?
2 piece? 1 piece? |

I've gotten mine at Go2Marine. Better pricing as well. I also stick with the traditional one piece. I feel it gives you better radial support at the aft end of the strut where it's needed from the radial loading from the prop. |

Deltaprop.com one of our sponsors has bearings. They show 1" shaft with 1 1/4 OD which is what mine is. Go2Marine does not list my size.
DeepBlueYatchSupply show multiple bearings with 1" ID and various lengths I used one piece with proper length. |

Love my OJ Vesconite bearings... I'd be hard pressed to go with the conventional bushings.

Is that a bad pun or a reference to the validity of calling these things bearings? In true CCF fashion we get 4 different answers!!! |

Anybody want to make an investment in a StrutPro? We could then rent it out to anyone on the site for $25 plus shipping. Take a while to make the money back but apparently these things works slicker then snot!!!

Steve, The person that told you how well they work, was he trying to sell it?? It's not easy to make a tool that only has .030 of brass wall thickness to press against! They work a couple times and then the mandrel needs to be refaced. Notice Jody doesn't even use one!!!!! |

Pete: nope the guy who told me how great they worked is a good friend of this site. He lives in Indy, said they had one at his old place of employment. He said they used it all the time. Made changing cutlass bearings a quick simple job. Pretty sure this guy wasn't trying to sell me one...
