Photobucket eliminated all my online library of photos with their extortion tactics. Starting again with imgur.
Here is the general engine room arrangement, saildrive with alternator to the right:
This is the original shaft (disconnected at the engine side in this picture), Bulflex on the damper pulley, Spicer spline shaft for extension and U joint on alternator:
That started to come loose in Maine on the trip south from Newfoundland, so I took it home, cut the U joint off and welded on another BulFlex. That required a peculiar adapter on the alternator shaft to make it look like a prop shaft:
New version installed. The extra stainless bit is intended to carry a guard to keep your arms out of it, but mainly to catch the shaft in case it breaks loose from the alternator end, and beats a hole in the bottom of the boat:
The Bulflex can move a little both in angle and in length. U joints (and CV joints) have to be kept slightly misaligned to keep them from Brinelling, the Bulflex doesn't, plus it has the vibration dampening.
Thanks
John
