Re: Terrible outdrive noise,shake
bondo.......I am very flattered by your compliment! How did you know I was from Brooklyn?<br /><br />My lower unit "blew". The pinion gear (in the lower unit) took-out the fwd gear in the lower unit.<br /><br />And yes, I rebuilt it w/o any special tools, and it ran fine all season. I replaced all the seals, u-joints and yoke also. When I drained the gear oil this fall it looked fine......<br /><br /><br />I tend to agree with Don S. Maybe it's running rough and it's not the outdrive.....<br /><br />If you still think it's the drive.......take it off and seperate it, remove the waterpump housing and impeller, you should then be able to turn the drive shaft by hand. It should turn smooth in neutral and both gears. Mine felt "awful" when I did this........That's when I knew it was the lower unit. My upper gears seemed ok, I just replaced the seals, yoke and u-joints in the upper and all gears bearings and bearing carrier in the lower half.
