Ummm,…no… I don’t know the make of the trans
But I’ll find out soon.
I do know that it is a 1980 with the Yanmar 3QM30 engine, it is the original (less than 700 hours on it). Lots in the original log book about replacement parts, the owner was quite dedicated to filling out the maintenance history. No mention of ever repowering it, so I assume the trans is original also. He seemed to be a stickler for periodic maintenance…good for me. Always hired the work done, tons of receipts to show for it.
Talked to a few other sailboat owners who all also concur that it is probably normal. Just the same, I figure it won’t hurt none to give it a good looking over, if I’m not careful, I might learn something.
Wish I could give a little more detail, but the engine manual is on the boat, about an hour from me here.
I expect that by poking around, I’ll find a little play in the prop shaft. In and out, up and down, side to side. I also expect a little gear lash…(or are most prop shafts chain driven?) …forward and reverse. I’ll report the findings to see if anyone thinks they are excessive.
Engine oil is OK, but I don’t remember seeing anyplace to check the trans fluid, I’ll look harder.
