As I mentioned on another thread recently,, had a new noise coming from what I thought was the gear on the way home from the San Juans, about 3 hours out from home.
It was a growly, grinding noise at speed and a noisy clatter at idle. Pulled a sample of trans fluid and shipped it off to the lab. Got that back yesterday, all the numbers pointed to,,, normal. Hmmm?
So just now I had a local mech come down and have a listen, showed him the report, we ran the thing in and out of gear, reved it up etc. Only noise we could hear, and he has good ears, unlike me, was aft of the trans.
There is a shaft bearing about a quarter inch directly in front of the stuffing box. I knew it was there but never though much about it, it was replaced as new when I was hauled for shaft and stuffing box work right after I bought the boat in spring of '16.
Mech is fairly certain that the bearing is the culprit. Will have to cut if off to begin with and then we will run it without the bearing and see how it behaves. He says it may be totally superfluous and in fact is in the way of changing packing in the box were it needed.
So that's where it is at the moment. He wasn't sure when he could get to it, being still pretty busy, but the weather has turned to rainy/squally already so not like it happened in July!
I have my fingers crossed. Will post further as I know more.
