Didn’t think to ask the diver where the shaft is in relation to the shaft log. I’ve just hopped off the boat to beat the thunderstorms into the house, so I’ll try to eyeball it from inside the boat later today or tomorrow. Coupling bolts are soaked in Kroil, and I’ll try to get them off tomorrow. Naturally they’re inaccessible from the inboard side on the port engine. If I have to take the battery boxes out, I’ll be unhappy. Any reason the coupling is assembled with the bolt heads aft instead of the nuts? The bolt heads jam right against the body of the coupling, so no impact wrench joy.

Re: Cutlass bearing or something else?
Depending on the gear the bolts may be too long to go in the coupling from the front. I had some impact sockets that made a trip to the bench grinder until they would fit. To keep from cracking them I’d use a break-over bar. I think they are 15/16’s but it’s been quite a few years since I had to do it for a job. It’s a suck job or sure. You should learn some new cuss words.

Re: Cutlass bearing or something else?
Took the boat out today with a buddy. Ran up and down the harbor, fast, slow and in between, straight and in circles, forward and reverse. We alternated between the helm and observing in the engine room. And saw very little. The port stuffing box clearly vibrates, but it’s not extreme. The starboard stuffing box vibrates too, although a little less. There is no perceptible flexing or vibration at the shaft log hose. Both stuffing boxes were cool, adjusted one to drip a little more, the other a little less. No humming, singing or squawking from the stuffing box, shaft or transmission. We happened across the harbor pumpout boat. We stopped for a pumpout so we could say we accomplished something. Have decided to go back where I was when this started - pack up the Admiral and some baloney sandwiches and head out for a few days. When I get back, I’ll check with my dive service to see if they have a diver/mechanic who can do a knowledgeable assessment of the cutlass bearings in the water. Thanks for all the suggestions. If I eventually find something, I’ll post it here.

Re: Cutlass bearing or something else?
Do you have spurs? When the bearings wear out the blades wear into each other. They get to a point that you swear you wrapped something in the wheel or you're having mechanical running gear issues. I have "shaft sharks" now. No moving parts. So far so good.
