My starter motor is failing. My first attempt to remove it will be this weekend. I will try and remove it with the engine in place, but fear that the aft end of the engine will have to be lifted to gain access. I am not looking forward to this process. Has anyone done this operation? Any good advice (other than tranquilizers)?

Matt I've done it, don't have to move engine. It may just need a good cleaning, contacts get gunked up

Alphee,
I had previously cleaned all of the connections and found that the problem persisted. I removed the starter motor two weekends ago. The bottom bolt was hidden from view/access by the motor mount and the hull. The motor mount is within 1/8 to 1/4 of an inch of the hull on the side with the starter. There was apparently no way to get at it in place so I raised the engine up one or two inches on the motor mounts. Even with the engine up (and the exhaust disconnected) the curvature of the hull made it so that the only wrench I could get on the nut was an open end wrench endwise. Perhaps the difference in this boat is the positioning of the engine. I don't know why my boat should be any different, but when the engine is aligned 2 of the 4 motor mounts are at the bottom of their travel and two are not far from their limits. one of the mounts is at the lateral limits of it's travel.
If I had to do it again I would buy a couple of box end wrenches and heat them up and bend them in attempt to hold them from the front of the engine. Even with the engine in the up positon, my un-bent box end wrench could not be made to get at the nut from the front side.
A far better solution would be to have a stud embedded in the engine at this location or have the housing tapped so that the bolt could thread into the housing and there would be no nut to hold from the back side. As usual time was short and I just reassembled the rebuilt starter in the same configuration that it was in to start with.
Thanks,
Matt
