Houston, we have a problem.
Well at least I have a problem. It appears I will need to haul out for a repair. So I wanted to get some insights to possible solutions.
Over time and a few bad installs of the cutlass bearing, the shaft log has been damaged. When I purchased Shanti the cutlass bearing was missing. Missing? you say? Yes, it had gotten loose and moved up inside the boat. Upon retrieval and repair is was noted that no dimples were made for the set screws to sit in. So a new cutlass was installed. Hopefully with dimples being drilled for the set screws to sit in (I was not present when repair was done). After my engine went out of alignment this last time I went in the water to check things out. What I found was, the dimples had been put in the cutlass, but in the wrong place so they were never functional. So the cutlass had dislodged again.
The cutlass was almost all the way out of the shaft log. The zinc preventing it from coming completely out. So I removed the prop and installed a new cutlass underwater. I drilled the dimples myself this time! When I put the new one in it fit snugly but not tight. And unfortunately the threads for the set screws (these are drilled into fiberglass) were fairly stripped. I was able to get the port side set screws fairly snug. But open turning the prop by hand, the cutlass rotated with the shaft … my heart sank!
So I will be hauling out for repair. My question is…how hard is this to fix? do I have to grind out the shaft log and install a new one? How about the set screws set into fiberglass, this seems to be a weak point in the set up. I’m thinking off grinding off the outer part of the shaft log. The part that sticks out from the hull and installing a bronze shaft log like this one http://www.buckalgonquin.com/pages/ProductPages/drivetrain/stern_bearing_page.html
Any thought or insights will be appreciated!
