Any of you 11 meter guys know anything about a intermediate shaft log bearing? I saw this term in the sales brochure I bought from Beacon for my 1984 11 meter express: "Intermediate shaft bearings, integral with shaft logs" It was listed under the " underwater gear features". Sure makes it sound like there is a bearing separate from the cutlass bearing. I would appreciate any picture or schematics of the drive system, or first hand knowledge

Also, how difficult should it be to turn the prop shaft when disconnected from the transmission? I can't turn mine by hand.

think of it as a little strut bearing or a carrier bearing it's between the strut and shaft log, you can take a strut bearing and cut it in half to replace them, Well you can on 80's Carvers,

I can turn mine hooked to the transmission...I'd say you need and alignment or bearings, Check in shaft for a bow between the struts.

Tony is correct. It's just a shorter version of the strut at your prop. It'll be between the main strut and the point at which the shaft enters the hull. If you can turn your shaft by hand, it could be a couple of things, alignment is out as Tony indicated but if you're on land and the strut bearing are dry, sometimes it takes a good tug to break them free before you can turn them manually. Are you trying to turn it from inside the hull or outside by grabing the prop?

Big D, I was trying to turn the shaft from inside the boat, disconnected from the transmission while the boat was in the water. I was checking the alignment which was .003.

Try wrapping something around the shaft or coupler and try spinning the shaft. Sometimes spinning by hand isn't the easiest thing to do given that you're trying to rotate a prop in water. If you can't spin it, there's gotta be a reason why. It shouln't be so tight that you can't spin it with some help. Will the other shaft spin? It should even if it's hooked up to the tranny.

I can turn it with a large pair of channel locks on the coupler. I have no indication of a problem like vibrations, high temperature of the components-checked with infra-red thermometer, nor any problem making full rated RPM. This is my first inboard boat and I had read that you should be able to turn the shafts fairly easy. Just trying to learn all the systems and there "normal" operation so I can detect the "abnormal" before it becomes an unpleasant surprise.

Perhaps the packing is tight ?

++1. It's amazing what you simply assume was already checked. Good one Paul.

Loosen off the packing nut to ensure the packing is not too tight and preventing you from turning the shaft.

That makes perfect sense to me. I will give it a try. Thanks. The obvious is most always overlooked!
