a side note: when installing a new damper and testing in the drive, do not get shaken, at times you need a load on the prop so the real test is dropping it in the water to load it. they will rattle in the drive, I was so worried i couldnt sleep last night lol, good to hear you got it together and ran it

Just a final update... Got everything reassembled, but still had a rattle when I ran it in the driveway. Eric recommended that I check timing and tune it up, which I did.
Replaced spark plugs, wires, adjusted timing at idle, and aligned . Dropped it in today and gave it the first run of the season and to my surprise, it ran amazingly well... rattle was gone. I did learn that I need a new steering cable, because my steering got much tighter over the winter. I unhooked the cable at the rudder and was able to turn the rudder easily, confirming it needed replacement. Ordered a new one from White Lake yesterday. |

Yeah, I loosened them up. I actually spoke to Eric and he walked me through everything. I needed to knock the tapered bolts loose with a dead-blow hammer to get it to move. I had taken the nut off the pinch clamp, but hadn't popped the bolt completely loose.
Everything is back together. I still have a rattle and spoke to Eric about that. I'm going to drop it in the water sometime this week or next weekend and see if it gets any better. He said that it may just be the planetary gear making noise, but there may not be an issue. Thanks again guys for all of the advice and thanks Eric for talking me through things on your day off. |

Matt, Did you take Chris's advice? The pinch clamps for the side to side will rust up pretty solid! |

Eric - here are the pics. I put one of the front mounts, 2 of the rear mounts, and one of my current alignment. I knocked it out a little yesterday while pulling the transmission...

call, I dont bite,
did you loosen the pinch bolts for your side to side? a good thing to remember is that there are 4 points the engine and trans rest on, if correct the weight will be divided by 4 and the weight will be dis-apated evenly. you want the engine resting evenly on these mounts. once aligned you want even pressure on the bottem nuts and dont want to tighten the nuts to where it will pull the mount and distort |

Up/Down is with the jack screws. There should be a square on top of them to turn. You might have to tap on the mount to get it to seat if you lower it. For side-to-side, I used a prybar between the mount & the block, or wherever I could get a bite. It doesn't take much force, at least mine did not.
Mark it with a pencil before you move it, so you don lose track of where you started from. it is easy to go the wrong direction! |

I think I'll be calling you shortly... I loosened all of the adjustment bolts on all of the mounts - front and back mounts, up/down, left/right adjustment bolts and I can't get the motor and tranny to move in the directions I need it to move. Don't know where and how to put pressure that won't damage anything. I need to move the back end down and to the left.

yeah, the springs between the flywheel and damper would've definitely created some problems had I not put the two washers (6 total) between each bolt and the plate. The washers created a nice even gap and gave the springs some breathing room. Great advice.
I'm headed out to try to tackle the alignment, replace fuel sending unit, and maybe drop it in for a test depending on how long it takes to get this stuff done. I'll keep you guys posted on the results. I'm a little nervous being that was my first experience in damper plate replacement. |

I think if you dont shim the damper out, we are going to see early failures on them.
i have no idea what knucklehead designed and put his stamp on the PCM Damper. it simply does not fit and is the only one in existance that will work with the 10 spline PCM trans. I called and was told to simply pull the damper in until its flush, nofcnway, thats wrong, doing it that way loads the plate and puts stress on it these simple alignment checks and adjustments are what keeps the boats in the water for the short boating season, the weekend warriors always seem to have thier boats at the shop....writing with a smerk |

SN and Eric - thanks again for all of the input and advice. I wasn't having much luck with tthe 90 degree swivel wrench, so I went with a 90 degree swivel ratchet and 1/2 socket and was able to get everything tightened up without drilling a hole. Here's a link to what I got:
Craftsman 90-degree Ratchet I printed out your how-to on alignment, so I'm going to tackle that tomorrow. Mine is a little off. Nothing too bad. If I run into any issues, I'll definitely let you know. Thanks again guys! Your advice is on point. |

or, you can drill a nice hole in the bellhousing which wont affect the integrity of the housing, and you can find plastic plugs at the hardware store, if you have access to the correct tools you could drill and tap th housing to 3/4 npt and pipe plug it.......thats if you cant find a suitable wrench that will work. i use a 90 degree swivel box end gear wrench.
now if you run into problems aligning we will also help you with that, i feel mis-alignment is one of the most important overlooked maintanance requirements on a boat and when aligned you will notice a difference if it was out of align. |

I was able to get everything taken apart, new damper plate off, new damper plate on with 2 Grade 8 washers on each shoulder bolt between the flywheel and new plate, and tranny back together. I left shoulder bolts finger tight, as recommended, to center the new plate.
I am trying to tighten the bolts now through the starter hole, but am having a hell of a time finding the right tool to do it. I bought some crows feet, but they aren't long enough to reach around the OD of the flywheel and damper plate to get to the bolt. Any recommendations on a tool I can buy and where to buy it to finish this job? |

Andy, the damper hub is smaller than the ID of the pilot on the crank so a tool will not work

MN - Another trick is to loosen up the mount adjustments while the tranny is up on the bench. It's much easier to break them loose there. I did not do this but wish I had. Breaking them loose in between the stringers was not fun.
Ps - Sorry for my tone above, didn't mean to be critical. |

I'd rather unbolt it from the cradle. The mounts will be 'feet' when you put it back together and maybe make for an extra handle. |

Thanks SN-
I'm definitely going to align everything once I'm done. Just figured I'd make sure that one way wasn't recommended. |

MN - Alignment should be rechecked anytime the transmission is removed, so it doesn't really matter wher you break it loose.

When I unbolt the tranny for removal, is it better to unbolt the tranny from the mounts or unbolt the mounts from the stringer. Didn't know if one would keep the alignment better than the other.

Hey Eric,
Can I use a clutch alignment tool and tighten the dampner to the flywheel before the engine is installed? |

6, it will be round instead of triangle, I was told you didnt have to space just simply pull it in with the bolts, I decided to space them with hardened washers of the same thickness, the round damper will line up with your bolt circle and you wont have to modify

Another couple of questions - I've read a bunch of threads about putting spacers between the flywheel and damper plate. Is my engine and transmission one that will require that method (93 Pro Boss with PCM 1.23)? If so, how many flat washers do you stack? Is the replacement plate that I ordered from PCM a direct bolt-on or will it require any modifications?
Sorry for the constant flow of questions, just stressing about taking this project on. |

SN - thanks for the heads up.
Eric - I guess I was having a blonde moment when looking for the starter because it was right in front of my face. No need to drill a hole in the bellhousing now. Can I just sneak a socket with an extension through the starter hole to tighten the bolts or does it require a special tool? Trying to make sure I have everything before I get into it. |

To drain the tranny - just turn it upside down when it's out. Don't bother with the drain plug, I have been told they aren't easy to get out.

Thanks for the info guys. I had my local Nautique dealer order the Damper Plate yesterday through PCM, so I should have it within a couple of days. I'll try to tackle this project next week or weekend, depending.
I'll probably do a good tranny draining while it's out since I'll be able to access the drain plug. Also going to check the alignment when I get it all back in. Anything else I should do while I've got it out. |

its important to get that damper plate centered or it will possibly side load the input shaft of the trans, its as important as prop shaft alignment

drill a 1" hole on the belhousing at the bolt location and sneak a socket through the hole, your local hardware sells plastic plugs to cover the hole....its well worth doing it this way if you cant sneak through the starter hole

MN - Eric surely will have the best method (tighten after transmission assembly), but you could use 3 countersink screws - tighten them down for centering, then replace those with the normal screws 1 at a time. I did this & it got the damper to within .001 on center.
