There is very, very little room behind the of a B32. The had to come out, first of all, and even then I couldn't really get any under there. I thought of tying a to my daughter's leg and stuffing her down a , but that didn't seem ... and there was some question about the shaft being torqued. So I cut it out of the with a sawzall. I sent out for a new one with a new matched coupling, and a kit for the PSS. The prop got overhauled. I picked up the y2gmf with a spanish made out of tubular webbing from a 2x4 spanning the top of the , and replaced all four mounts. The damn things might as well be made of gold. The cutlass bearing got cut out with a hacksaw blade(only way) and replaced. Alignment was a little time consuming, but not as tricky as I thought. I just kept moving back and forth from the with a prybar and some wrenches(engine) and cramming myself into the locker with a .001 feeler gauge.(coupling) This took about an hour. It was very difficult to get enough on the new PSS baffle, but finally that was done as well.
The prop turns with no binding in neutral (on the hard, obviously) and while she does make a few cups of after six hours of motoring, I consider the a success.
Incidentally, I never did find out how the shaft backed out, but I suspect the motor mounts. Whatever. Considering the age of everything(!) this had to happen anyway.
The total cost was something on the order of $1,400 dollars, largely because of those damn motor mounts. $245 each? Really, ? For frickin' rubber? Seriously? But I had received solemn advise not to go with aftermarket. (sigh) ok. Total time was several days, and a LOT of headscratching. Let me know if you want to turn a nut while lying face down, feet extended above you toward the stern, with arm fully extended, over a gaping, bottomless hole, with a ratchet plus extension. I can give endless .

Boat: 1979 Bristol 35.5 CB | made in 2 halves? The stern tube itself may be leaking where it joins the . If the PSS , it usually throws a black stripe perpendicular to the shaft. Check that the carbon face is not damaged. |

Boat: 1966 Bristol 32 | in a gradual way. This has worked out quite well. I have the luxury of sailing on inland waters while figuring things out and still have a couple of seasons to go before I plan on doing any coastal cruising. I have found some interesting threads here regarding the pros and cons of the Bristol 32 and I think this thread gives a good indication of the very poor access to the , drive train, and stuffing box on the Bristol 32. My boat got some extensive upgrades around 1995 and is in quite good condition. The only I did prior to going sailing was to cut out the plywood/fibreglass for the aft and it like the original design. After 2 seasons, I think it's time to do the stuffing box. Remarkably, I suspect this hasn't been done since the mid nineties when the 3 cylinder Yanmar cooled engine was installed, about 900 hours ago. I've been keeping a very close watch on the stuffing box and the shaft log looks good but the drip rate was quite high when underway, probably slightly more than one drip per second. Anyway, just getting access to the stuffing box seems like mission impossible. With the three cylinder engine I probably have even less room to than Mainebristol. I find this situation unacceptable from a design stand point and will be looking at ways to get better access in the future. I seeing some photos of a modified B32 with what looked like an access built into the cockpit floor. To get that to on my boat would require moving the aft. I think that's what was done on the B32 I mentioned but it was probably a smaller custom built tank. My present plan is to remove the screws holding the engine to the , the entire engine, mounts, and drive shaft forward up a 2X6 , then take it from there. This is totally nuts, of course, but I don't see a better way to do it. Hopefully, once the engine is pulled forward I can come up with a way to get better access in the future. The will be starting in a couple of weeks and I plan on some progress reports on a new thread but in the meantime, any tips, comments or warnings? |

Boat: Bristol 32 | in there? Or a hot water , maybe? I've got to port, and I had a hot water heater to starboard, but I removed the water heater. With that out of the way, I was able to gain access. Painful access, but access none the less. With my feet jammed up inside the locker toward the stern, lying on my belly, I could get in there with whatever tools I needed. Stuff a blanket or something big down the hole so you don't drop your tools down there. I'm six feet, and an expanding 245 pounds. I'm fifty six. I could just manage this without major injury. If you do pull your engine, take the opportunity to replace the engine mounts, which harden over time. These are very, very expensive, so it helps to pull out some nose hairs to get in the proper mood before you order them. Be sure to get the proper replacements! This can be screwed up! Take your time aligning your engine. This has to be done right. For what it's worth, I picked mine up with some tubular webbing strung over a 2by4 place over the companionway. This whole process was a pain, but it can be done. Please let me know if you have any questions. MaineBristol, B32 "Eider" |

Boat: Bristol 32 | feature endless well-meaning epistles without really illustrating things in a meaningful way, if that makes sense. Sorry. |

Boat: 1966 Bristol 32 | and in the starboard locker. The port locker just has the manual so will take a closer look there. My initial impression regarding access through the locker wasn't good but as you managed to get some things done from there I will give it a shot. Working through the engine bay I could barely get a wrench on the stuffing box and trying to apply enough torque to even loosen the lock nut proved impossible on my first attempt. Even assuming I can get the stuffing box nuts loose I don't see a way to get adequate access to re-pack it without dragging everything forward. Once I get back to the boat in about a week I will check the locker access. I understand the comments regarding the engine mounts and a PSS system. If I end up pulling all kinds of things apart it would be best to spend some now and not have to worry so much about those items in the future. |
