I thought I'd share this weeks maintenance on Loki.
I contracted a local mobile marine mechanical group (very reputable) to replace the shaft seal on Loki. The seal replacement uncovered issues with the shaft coupling keyway, which lead to pulling the shaft, which uncovered wobble in the bedding of the strut. I had injected the area with epoxy about 5 years ago, but the wobble had reappeared. I decided to move on with a permanent fix.
The mech ground out the glass that covered the strut bolting on the inside of the hull to expose the true issue with the wobble.
When the strut was originally installed, three bolts were inserted through holes in the strut to hold it in place, then totally glassed in on the inside of the hull. The bolts are not attached to the strut at all, simple slid through the holes.
Looking up from the outside of the hull:
You can see through the gap, the bolting run through the strut on the inside of the hull. I assume this was done by the stoners in Santa Cruz in 1990 when the hull was outfitted.
The strut has been removed. I'll have a bronze plate welded to the end, and bed the strut properly while aligning the shaft.
And so goes this years boat maintenance budget.
