Due to some some things in life, I had to go ahead and pull my boat out and winterize it. It's a '03 Captiva 232, 350 MAG, Bravo III with 235 hours, and I used it a bunch this year with basically no issues. I had started a thread earlier this year about a squeaking sound that I would hear intermittently on a cold start, but aside from that, the boat worked well, and made no noises. last winter, the boat had the entire transom assembly replaced, so gimbal ring/bearing, and all bellows are new.
I had the boat running out of the water, with the muffs on, and noticed a noise from the outdrive. It wasn't even loud enough to hear from inside the boat, which is likely why I've never heard it, but standing at the back of the boat it was making what I'd call a clattering noise from the outdrive. Something I'd equate to as a bearing noise, and I could put my hand on the outdrive and actually feel it.
I drained the oil through a white tee shirt, and surprisingly didn't see any metal shavings. The magnetic plugs had a very small amount on them, around a normal amount. When I filled the outdrive back up, I noticed it started pushing shavings out the top hole when it filled up. No "chunks" or anything, but shavings larger than I like to see.
I don't know much about what's inside these outdrives, but I do know the shaft spins in neutral, and there has to be bearings up there, so what kind of damage can I expect there to be inside there? I'm sure this isn't going to be an inexpensive repair.
