Ok, trying to remove the coupling and what a PITA  So far I am able to move the coupling little less than half way from the shaft. As I was cranking on the bolts evenly, I notice transmission oil dripping from the inner transmission seal. Do I have a problem? Is my seal shot? Do appreciate it. Thanks Edit: when I released all bolts and cleaned up the oil, no more drips and seal looks good. http://s1279.photobucket.com/user/kostaki98/media/Mobile%20Uploads/F58EAA6E-C1BD-446E-A9D6-1119FE8F4D28_zpsj7zj15bh.jpg.html" rel="nofollow">  http://s1279.photobucket.com/user/kostaki98/media/Mobile%20Uploads/FFBEE3DB-B93F-4963-9B5E-D0F84DCA17EC_zpskgdt8lri.jpg.html" rel="nofollow">  http://s1279.photobucket.com/user/kostaki98/media/Mobile%20Uploads/6057B2DB-935F-4DC9-B388-DAABE4CEBD3D_zpsmqek6owh.jpg.html" rel="nofollow">  (I rotated the transmission coupling, leaking at bottom) http://s1279.photobucket.com/user/kostaki98/media/Mobile%20Uploads/58F0F2C6-4E46-47DF-8A85-E5E1F4BF5F13_zpsksy34g5o.jpg.html" rel="nofollow">  (I rotated the transmission coupling, leaking at bottom) Kostas N 84N2001 ------------- Kostas http://www.correctcraftfan.com/diaries/details.asp?ID=6700&sort=&pagenum=1" rel="nofollow - 1984 Ski Nautique 2001 |

I was able to find a similar problem posted here but no outcome if this person actual replaced the seal or if it self fixed. Anyone with any info would be great.

Ok, spoke with skidim and told me to keep an eye on it since it stopped leaking, that's good. Now, I was able to get the coupling out but ended up damaging it when trying to install it back onto the shaft. I believe I know the issue......I was trying to install the coupling with the key in place on the shaft. I was able to get 3/4 of the coupling onto the shaft but no luck with the rest. I did heat up the coupling for one hour at 500 degrees and placed an ice pack on the shaft. Now, question? Shouldn't I be installing the coupling on the shaft all the way and then drive the key? Let me know, do appreciate. Going to order a new coupling from skidim tomorrow thanks Kostas N 84SN2001 ------------- Kostas http://www.correctcraftfan.com/diaries/details.asp?ID=6700&sort=&pagenum=1" rel="nofollow - 1984 Ski Nautique 2001 |

| When I did mine it was one move, when it stopped that was where it was and it wasn't going anywhere. It wasn't exactly where I wanted it, but close enough. If I do it again I'm going to try and go past because it isn't that hard to put the sock back in and push it out to where I want it. |

Well I am at round 2 of this with no success  I had the new coupler in the oven for 2 hours at 550 degrees and was unable to slide the coupler onto the drive shaft. I even had ice on the drive shaft thinking that would work. Going to trying one more time tonight without ice and if it does not slide on then I will either scrap the shaft & coupling or sell if anyone is interested.

| You may need to run that by the machine shop first, they have to be within a few thousandths (.000) for it to work. Mine came off of the shaft it was on so I could change the strut bearings. |

Kostas, In the spring I removed the drive shaft from the coupler to replace my strut bushings and replace the packing on the rudder and the drive shaft. When I went to reinstall the coupler I used a propane out door cooker. Half a beer was more than enuf to get the coupler really HOT! I picked it up with a pair of pliers and up into the boat, with a pair of heavy welding gloves the coupler slid right on with the key in place no problem. It was probably too hot as I could feel my hands burning thru the gloves! But the shaft and coupler are tight! Just another approach! Good luck! John ------------- Old school goin back to school! |

Ice is not going to chill the shaft enough. Heat the shaft is some manner and put the shaft in the freezer. Assuming you had a deep freeze. Heat expands, cold contracts. ------------- |

Well the 3rd attemp was no good I believe its not getting hot enough, electric oven at 550 degrees. Unfortunately I do not have a freezer larger enough for the drive shaft. John, I remeber you telling me that at Tims. My buddy has a deep frier cooker that I will give it a final try. I just want to be able to look back and see my new 540 prop on  Below are some pictures of the drive shaft and the new coupler. Only was able to get it about a 1/4". Thanks for your input, appreciate it. http://s1279.photobucket.com/user/kostaki98/media/Mobile%20Uploads/9A4510C6-EF0A-4399-98F3-B424BCB9F7D2_zpszxzwtpon.jpg.html" rel="nofollow">  http://s1279.photobucket.com/user/kostaki98/media/Mobile%20Uploads/31E3C425-1349-493A-87D0-166AF4AD0D93_zpsovdhs37h.jpg.html" rel="nofollow">  http://s1279.photobucket.com/user/kostaki98/media/Mobile%20Uploads/C4320590-05D4-4254-BC9F-D30209191965_zpsafo8fpao.jpg.html" rel="nofollow">  ------------- Kostas http://www.correctcraftfan.com/diaries/details.asp?ID=6700&sort=&pagenum=1" rel="nofollow - 1984 Ski Nautique 2001 |

Don is on the right track. A new coupling must, in my opinion, be >fit and faced< upon the shaft. Take it to a prop shop and they will install the coupling, set the counter bore and grub screw locations correctly, chuck it up in the lathe and face the coupling, check and true the shaft then index and dissemble the pieces ready for you to install. Add another Bill to blue print the prop while you are at it. Balance the price of that service regionally against a pre-fit ARE set up and follow your wallet. Call your local prop shop and ask for an estimate. The guy I use is expensive but Rain Man precise. It would be perfect but within range of the ARE cost wise. You should still do the prop though.. ------------- Jesus was a bare-footer............. |

Having the Shaft and Coupling clean and burr free is very important. The clearance on this interference fit is smaller than zero. Anything that sticks up will bugger up your install. Take really fine emery cloth and make sure the finish is smooth on the shaft and the coupler inside surface. Do not sand it or you will reduce your interference fit. Just smooth any rough spots or high spots. Your picture shows damage or gauling on the shaft and coupler. You will need to smooth that back out. On install it needs to be one smooth move. Once the hot coupler touches heat transfers quickly and the shaft will grow locking you in place. You have to be faster than the heat transfer. Should be 1-5 second install. Make sure the key is fitted both to the shaft and the coupler, if the key is tight you will not win. The key cant be tight or sloppy. The one hour in the oven might work but I would use a gas stove top or even a coleman stove to heat the coupler, set it on direct flame, it will heat in 4 or 5 minutes, Best of luck. |

Try 3 hours in the oven. Ditch the ice. You might be causing the shaft to sweat and if so you're screwed. ------------- |

I'd break out the Weber grill,but there isn't going to be a next time for me,I'd get an A.R.E. set up. But at least you would be right next to the boat,no need to run thru the house heading toward the boat and cooling the coupler as you go ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Well no luck over the weekend. I cleaned the heck out of it with emery cloth and tried the propain cooker for 1 plus hours with zero luck. The best was back in my the oven for 3 hours and no ice but still fell short. Going to get a quote on the A.R.E system from skidim and decide then what to do. Wife is tired of me talking about my "shaft"  So I have a welder buddy coming over tomorrow and will give it a last try. I talked with a machine shop to take a look but wanted around $125, I rather put the money on the A.R.E system, wasted enough time already. If I go this route, I will try to sell the shaft and 2 couplers and let someone else give it a try. Not sure what used parts go for, any idea or I should not even bother?

I would be willing to bet that your shaft has been replaced before, and its a few thousands off from the factory one..After some heat and ice or freezer time u shouldnt be struggling with it like you have been. Its and interference fit so after expanding the new collar with heat and somewhat shrinking the shaft with freezer and still no go... than the diameters are deff too far apart imop. ------------- 1977 MasterCraft Stars&Stripes 1994 Ski Nautique 2000 Super Air Nautique 1986 Ski Nautique 2001 1999 Sport Nautique gt40 current |

Sorry about your troubles, something is off and a Micrometer should show you where to start fixing. I switched to the ARE after my shaft was ruined along with a prop. Very easy install and very high quality. |

I was so pissed off at the hassle it was to remove the coupling and then having read beforehand this business of heating/cooling things that I opted for one of these: http://catalog.buckalgonquin.com/item/transmission-couplers-4/transmission-couplers/50401s?&plpver=10&origin=advsrch&by=prod&filter=0&categid=1537&prodid=1312" rel="nofollow - split coupling Took the shaft and coupling to a machine shop and they trued them together and also declared the shaft straight on arrival. I also went for one of these to avoid any hassles with shaft packing: http://www.californiamarine.com/part_details.asp?category=Shaft+Log+Stuffing+Boxes&subcategory=Parts+and+Accessories&partnumber=140430" rel="nofollow - shaft log |

Well finally I was able to install the coupler  Had the wife cook it for 4 hours and with assistance from her, it actually slid right on with no problem. I was able to match up the set screw but going to need to replace one of them since it snapped off when I tried to use them to seat the coupler in its exact place, no biggy Thanks for everyone's input and support and not letting me say f'it  ------------- Kostas http://www.correctcraftfan.com/diaries/details.asp?ID=6700&sort=&pagenum=1" rel="nofollow - 1984 Ski Nautique 2001 |

Well I finally installed the 540 prop today Thanks to Pete's "proper prop installation" and Eric's "alignment" forum topics Of course I did come up with an issue After installing the new prop, I notice the prop is now touching the trailer. I took off the new prop and installed the old and it clears the trailer little more than a 1/4". Sooooo after some thinking, could I lower the rear of the trailer support to get atiquite clearance? Was thinking 3/4" stainless steel plates under the rail where the rear support bolts up. Any concerns??

You did the cotter pin wrong. The prop-hull clearance picture doesn't make any sense, you're not measuring the largest diameter which is at the blade tip (where it also hits the trailer). I have an 88 trailer and 540 and my clearance is quite minimal. The 84 trailer/prop guard might be naturally closer and/or your boat may be further forward than it should. 3/4" spacer is probably overkill. You'll never have less clearance than you do now so even minimal would be sufficient. I'd be comfortable with as little as 1/4". Can't say I know my clearance off the top of my head. ------------- |

| Clearance from my prop to trailer is about 1/4". Like HW said, it can't physically get any closer once the boat is sitting all the way forward on the trailer. Most of the 80's prop guards seemed to be spaced lower with a few washers. |

Thanks guys..... I was just snapping some pics to give you guys an idea of where the prop was positioned. The boat normaly sits even with edge of the bunks. I do need to push the boat 2" forward to make it flush. I was thinking a plate of some sort to give it more even surface space then just washers. I know, overkill. Now you got me thinking about the counter pin, how did I install it wrong? Been trying to find pictures to compare. I did have to back off the nutts to allign the counter pin with the hole. Is that ok? Thanks again! ------------- Kostas http://www.correctcraftfan.com/diaries/details.asp?ID=6700&sort=&pagenum=1" rel="nofollow - 1984 Ski Nautique 2001 |

You can also put spacers between the bunks and your trailer in the rear. It is only 2 bolts on each side. I say that because of the number of times I drag the trailer guard on driveways. |

HW is correct. It's not the radial position of the cotter pin but rather the direction you bent it. You bent it around the nut which is not the proper method. A cotter pin should be bent with one leg aft over the shaft and the other leg forward over the nut towards the prop hub.

For those who may not know the difference in the correct way to install the cotter pin, here's the explanation. Basically it comes down to tightness of the cotter pin. With the pin installed as shown, the eye is engaged in the grove of the nut and the legs are bent over so they are tight. If installed incorrectly, there is a good chance that vibration will "eat" through the pin and you will loose it. Then you can loose the nut as well as the prop if it's not properly lapped/seated to the shaft. I have seen plenty of boats were the cotter pin is gone. We even had a CCfan member loose his brand new prop! Keeping the nut in place is important since there are occasions where the nut is backed off slightly so the groves line up with the cotter pin hole. Backing the nut off is normal practice since the nut is really used to seat the prop on it's taper. A properly seated lapped prop really doesn't need the nut. It's there as a back up. ------------- /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 < |
