Peter,
Did this last spring with new shaft logs also. Be sure you can slide the shaft far enough back to clear the hose after the coupler is removed and watch for the rudders. Removing the coupler may be a chore depending on how tight it is to the shaft. Once the shaft is free it will slide backwards with a little water tossed onto the cutlass bearing while being rotated and pulled. My brother and I did it in about 90 minutes as a team 1 in the boat and the other outside screaming...MORE ? MORE? WHAT...I cant hear you! |

If it is a solid coupler, suggest you order a split coupler to replace it.
If you are changed the hose because it has degraded, beter plan on doing the other side, too. In that case, get two split couplers, not one.
Best to remove the props before starting.
Warn the family, your vocabulary will suddenly expand with a plethora of new four letter words and their cousins.....
If someone had the foresight to install split couplers, it should be straight forward and you could get both sides done in an afternoon. Send them a thank you note.
I use the T-bolt clamps on those hoses, two on each end. Due to finding the 'regular hose clamps' separated one day, way offshore. They parted on the 'bottom' where most of us can't see without an inspection mirror. Bought one of those, too, and it lives on the boat. |

look here:
http://buckalgonquin.com/pages/ProductPages/Shafting/transmission_couplers_page. html
The slipt coupler has two thru bolts that 'clamp' onto the shaft. The 'white' area of the pics, in the link, is where the 'split' is. |

My last removal took an angle grinder with a narrow metal cutting blade, two full cuts on the length of the coupler, and then an air hammer to knock off the coupler pieces. It was 10 years old, and lots of salt rusting. I did coal tar epoxy it a few years before. The setscrews were not to be found...
On new ones, I was successful in pressing off the coupler by using two studs and 4 nuts, using the tranny coupler as the fixed press. And, you need some sockets as the drifts in the center. |

I had to do the die grinder with a cutoff wheel, too, at about 12 years. And the split couplers went on afterwards. Got away with one cut and Al's BFH with a chisel to pry it open just enough for it to slide off. |

Back off the coupler from the gear, insert a shallow socket in alignment with the shaft then bolt the coupler back up, rotating and tightening one bolt at a time and repeating until it spits the shaft right out. You might want to get some longer bolts for this process but it never fails, even with tapered shafts. |

Peter, this is a good time to think about dripless packing if you have some extra $$$ and want a nice upgrade. |

Note that, even with a split coupler, you still have to muscle it on and off the shaft. Mine needed a bit of sanding to go on since they deliberately make them a few thousandths too small, so they can be fitted.

How are your cutlass bearings, stuffing box, shaft logs and other replacable parts? That area of concern is your primary need if you had to pull the shaft out for any reason |

I shouldn't be reading about stuffing boxes now. This is the first year I'm leaving the boat in the water. I'll winterize end of december and run adjitaters and a heater in engine room. I just did the packing this spring. Everthing looks fine... Though I'm bring my inspection mirror wednesday when I fish... |

Well, Scott, you asked... I am just thinking about what I would need to remove in order to pull the shaft and make sure was good before I replaced it again.
BTW: I saw a guy in a boat next to me pull up a big striper...maybe 30-32"...look at it, and toss it back into the water |
