Drive Train Squeal

I feel like I've been posting too many "what should I do about this?" threads lately, but the feedback has been valuable.

Anyway, when I bought my boat last fall (1981 Spirit 28, Yanmar 2QM15 engine, PSS shaft seal, three blade prop), I noticed that when sailing above about 4 knots, with the transmission in neutral, I could hear a faint squeal (almost sounded like wind whistling over the backstay, but noise went away when transmission was placed into gear, so I knew it was related to shaft rotation). I didn't think much of it, since there was no sound under power, and I could make it stop by putting to the transmission in gear.

But lately, I've noticed that I can hear the same or similar noise under power (in forward gear), as well as under sail (in neutral). The sound is fairly faint -- in fact, it's almost drowned out by the engine noise.

Sound to me like a bearing, but I don't know the exact source. My next plan is to crawl into the engine compartment while underway and have a good listen.

I'm pretty sure it's got the Kanzaki-Hurth transmission. If the noise is coming from there, what are my options?

Any other suggestions?

Re: Drive Train Squeal

It could be transmission, it could be engine, it could be just a vibration noise of something rubbing in a rhythm.
I have the same thing in fwd gear only, sounds like crickets chirping but only at certain higher RPMs which makes me think "It's just a weird vibration not the transmission" but I'm probably wrong.

Good luck, please fill us in on what you find.
