So in the fall, end of the season maintenance, I (as usual) changed my lower unit fluid only to find about an ounce of water in the gear case. Yesterday I finally did the inspection and found a very small portion of fishing line outside of the seal. I decided to remove the lower unit to get the seals checked/ replaced and I was also going to change the water pump.

Tragedy #1 was breaking the 7/16 bolt off in the rear of the lower unit.
Tragedy #2 was removing the water pump to find a broken bolt on the upper seal/bearing housing, still not sure how that broke and it had obviously been like for a long time.

The (I guess) lucky side of this story, I carried my heap of problems to my local mechanic and had a lengthy discussion over my options. We pressure tested the lower unit and to my surprise it held pressure fine (so I'll be keeping a close look at that).

The broken bolt in the exhaust housing was a whole challenge of its own.
I drilled, soaked, heated and beat on it but no luck so it got drilled out and re-threaded(and of course it was broken flush so options were limited). The broken bolt in the bearing housing will just have to stay broken as there's a fair amount of corrosion so I'm guessing the other 2 bolts would surely ring off and i'm going to let my chips ride on the pressure test and more frequent fluid checks.

All in all today sucked.

Doesn't sound like fun at all, but you got through it. - Been there - done that. It could have been much worse. (beats having to put a new motor on)
