This should probably go in the maintenance section. Go there and there is a icon over to the left for starting new topics. Is the shaft bent? Just wondering why you're pulling it. The hardest part is getting the coupling off the prop shaft since it should be a heat shrink it fit. There's a trick that many have used. A deep socket in the middle betwen the two coupling halves just smaller than the prop shaft and then long threaded rod w/nuts where you removed the bolts holding the halves together. Tightening the threaded rod nuts will then push the shaft out of the coupling. I suggest fine thread to give you a better mechanical advantage. |

I see you did a edit and added that you hit a stump. How's the strut? Prop gone too?
Since the shaft is bent, the best is to get new but some have had good luck with straightening. If you do go new, it may be easier to just get the Sawsall out and cut the shaft just aft of the coupling. The easy shaft to put back on the boat is a A.R.E. They have a taper on both ends for the prop and the coupling. It makes the coupling real easy to put back on. No heating for the shrink fit. Welcome to CCfan. |

Thanks for your help. Will the rudder have to be removed?

Yes you'll need to drop the rudder.
Get your first name up in your profile. Most here go by them and I have a bad habbit of calling people "no name" if they haven't included it!! |

Yes, you'll need to remove the gas tank unless your arms are small enough to fit back under it. You'll find a center bolt as well as a clamp bolt on the tiller arm. Remove them and the rudder may drop so stick a 2x4 under the rudder outside the boat. If it doesn't drop, you'll se some rather large nuts on top of the rudder port. One is the packing nut and the thin one below is it's jam nut. Loosen them and the rudder will then come out.
This is a excellent time to do a repack of both your rudder port and your prop shaft packing gland. |

Come on Pete, dont get so caught up in calling him "no name" that you neglect to notice what kind of boat he has! There will be almost a foot of clearance between the tank and rudder on the v-hulled Martinique. No skinny arms required! |

Tim,
Knowing you and your knowledge base, you're probably correct. Yes, I spoke out of turn here but how big is the tank in it? Also I did know what boat he has but personally have never been into the aft end of one. So, back to the original question if the tank needs to come out to get the rudder dropped. Probably not. Take a look and report back. I'm curious now!! |

You can get a good look at a Martnique's ass by sticking your head up it..but I'd rather take Tim's word on it.
...or something like that (disclosure...if you haven't seen Tommy Boy...don't try to make sense out of that) |

Like Nedlutz said, the v-hulls should all be very similar. The gas tank sits on supports that rest on top of the secondary stringers. The secondary stringers are about 9" tall. The v-hull continues to taper most of the way to the keel, so you end up with a ton of vertical room under the tank. More than enough to reach in and fiddle with the rudder. Borrowed from Greg: |

Redneck time - We hit a submerged log a couple weeks ago. Bowed the shaft & I believe moved the strut too. Believe it or not, the Acme prop is undamaged - heck of an alloy!
I made some V blocks from angle iron (welded flats to the bottoms). The shaft was bowed about .009 inch. Found the high spot with a dial indicator. My son & I used our weight to straighten the shaft - got it down to .0015 inch. After realignment it runs smooth, but the helm want to pull to port a little - I think the stut is bent - I'll save that for a winter project. Moral of my story - It is possible to straighten the shaft yourself if it is only slightly bent. |
