I just put on my new Acme 540 and can't get it far enough up the shaft to get the cotter in. I am using all of my strength to tighten down the nut without stripping it. Anyone got a suggestion other than for me to get some more muscle?
Do you think that it could be the alignment of the woodruff key holding the prop back? I have about an inch between my prop and the mount that holds the drive shaft, i tried finding out the real name of it but failed. ------------- "I'm planning to bring my girl that rides on a trailer with me and leave my girl that complains about camping at home" |

2K4, Take the prop off and try it without the key. This will confirm if the key is to wide. If it is then the top of the key needs to be filed down. If it's not the key, I have seen where combination of the taper on the shaft and the prop are off enough that the cotter pin won't go in the castilated nut. You can ether get a brass Nyloc nut or file the slot in the nut slightly deeper. ------------- /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 < |

Not sure how your prop shaft is cut for the key but mine has the keyway rounded on the end closest to the prop strut. You have to be careful if you're putting the key in while sliding the prop on and not letting the key slide toward the front (strut) because the front edge of it will raise and not allow the prop to seat fully. Put the prop on and then slide the key into the keyway. If the key doesn't fit, you might have to lightly file or sand it so it just fits.
Pete is right, try it without the key to make sure that the prop itself fits. Then put the key in. You don't have to worry about stripping that nut. If you can that, Metropolis and Lois Lane are trying to find you. That doesn't have to be that tight anyway. The castle nut is just snugged up. |

Would a little lubrication on the shaft hurt? I know they make that stuff to put on the shaft to prevent the prop from freezing on to the shaft. Tim B. would be the perfect person to chim in here.

Ken, YES the lub or anti seeze WILL hurt. The taper on the shaft and prop transmit the torque from the engine to the prop. Don't do it because you will probably shear the key and mess up the shaft and prop. The tight fit is why they make prop pullers. ------------- /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 < |

That is what was wrong. The key was to far up and wouldnt let the prop go far enough. I carefully used a hammer and a piece of wood to tap the key down then tightened up the nut ------------- "I'm planning to bring my girl that rides on a trailer with me and leave my girl that complains about camping at home" |

btw- that thing that holds the prop shaft in place is called a strut. ------------- Former: http://www.correctcraftfan.com/diaries/details.asp?ID=759" rel="nofollow - '86 Nautique http://www.correctcraftfan.com/diaries/details.asp?ID=507" rel="nofollow - '65 Barracuda |

Thanks. At the time of that post i had searched all over ski dim trying to figure out what the correct name of that was. Strut works for me ------------- "I'm planning to bring my girl that rides on a trailer with me and leave my girl that complains about camping at home" |
