Pulled my transmission and jacked up the rear of the engine in the process. I loosened the pinch bolts on the engine mounts to allow the engine to rotate up, but it appears one side didn't free up and rotate. Do I need to replace it? I'm kinda thinking it will straighten back out when set down--obviously will need to check alignment though. The bent one--  The good one

It's fine - the rubber is doing the flexing. Good luck on the tranny rebuild. Make sure & do an accurate shaft alignment when you reinstall. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

| You loosened the nut but I can see you didn’t tap the pinch bolt in. Most of the time you have to give the bolt a little tap to move the pinch bolt in to release the mount stud. |

SNobsessed thanks, I sent the transmission off to Fantastic Finish Marine and have heard nothing about good things from them so I'm just looking forward to getting everything back together now. gun-driver I guess I'm not quite following you on tapping the pinch bolt. Unless I'm confused on what the pinch bolt is (which I probably am) I thought it was the threaded stud in the block where the horizontal shaft to the engine mount goes in (can barely see it behind the spark plug wires in the pics). Or is it the larger nut on the top of the vertical engine mount stud... because I only loosed those when I saw the one was bending/flexing. So that may have been my problem to begin with if that's the case |

| It's the horizontal bolt in the mount attached to the block. After you loosen it you need to tap it a few times with a hammer to expand the bore where the horizontal eye bolt (heim joint) is inserted into. That allows the eye bolt to rotate as you jack one end of the motor up. It's frozen in the bore and didn't rotate and that's why the outer bushing bolt got twisted. |

| Gotcha, that was my problem then. Thanks a bunch. |

If you remove the pinch bolt and clean it up then apply some anti seize and make sure the pineal type mount rotates and slides in and out freely it makes it a whole lot easier to do a shaft alignment. Which by the way is in your near future when the transmission comes back. Now would also be a good time to tear down the rear mounts clean and anti-seize, it sure makes alignment jobs easier when the mounts move easily. |

| Awesome, thanks for the advise. I'm not really lookin forward to alignment, but I do want to have everything ready to go for when I get the transmission back. Can't wait to get back on the water. |

| My cutlass bushing was suspect also so I'm replacing that and re-packing the shaft seal and rudder while I have everything apart. Hopefully will all run out nice and smooth when I get it back together. |

It's really easy as long as you understand the concept of keeping the shaft straight. Have you looked at the video?? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Go to the video section and you will find the alignment 101. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Thought I'd follow up. After pulling the rear mounts apart for cleaning and watching the alignment video it was pretty easy to understand the alignment process. The front right mount did take some extra persuading to free up, even with the pinch bolt properly released. I was kind of surprised that the engine is pushed nearly all the way to the right on the mounts (I was dumb and never looked to see where it was prior to pulling the tranny). But the shaft/coupler is properly aligned and the boat pulls hard with no vibrations. The Transmission was a little late getting back to me which set me back a couple weeks for when I was able to install it due to other obligations, but I couldn't be happier with the rebuild and am more than happy to be back on the water. |

It is not uncommon for either stringers or log/strut to be placed just crooked enough from the factory to require a good portion of the mounts range... But I assume that you aligned the engine to the shaft where the shaft spin freely in the bore of the strut? If not, you just dialed in a bunch of misalignment. I am also assuming that you checked to see that the shaft was fairly concentric to the log when spinning freely in the strut? Misalignment will quell vibration, not cause (or exacerbate) it. |

| Yep, I did make sure it was concentric and spinning freely. After buttoning everything up it still spins freely as well. Good to know about the vibrations though, I just assumed a misaligned boat would vibrate badly. |

I had a similar problem with my '95 after my wife had her little episode with the rocks. Every thing lined up right but the motor was shifted all the way right. I found that the shaft was not in line with the rudder it was off centered when looked at from behind the rudder. Some adjustment with the strut got everything in line. So what I'm saying is to look at the shaft from the rear and see if it straight down the center line of the boat. You should be able to look straight down the rudder, shaft end, strut, Skaggs. Hope that makes sense. |

If the prop shaft is centered in the log, that's as good as it gets for strut position. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |
