This morning I pulled out of the 5mph to drive to our riding spot, as I accelerated we heard a loud noise coming from the v-drive/ tranny area and I backed off...it sounded like a bunch of nails being shook in a tin can.
I would accelerate/ take off to about 10mph and the noise was still there. After a few more take off attempts and the noise still being there, I said screw it and went a little faster and the noise went away. The noise was there for the first 30 min of riding then went away, but came back a little later in the day, and went away again.
Last weekend my serpintine belt frayed and I just replaced it, this was the first trip out with the new belt but all looked/worked fine with that....(just thought I'd give a little back round).
Any thoughts as to what the loud noise could be? ...and why it goes away after about the 10 mph mark when the boat gets out of the hole?
