Rockie,
You mentioned a leak in your drive. I just installed my new Imco, oil leak, where did you find your leak. Right now I think I might have tightened the filler plug too tight and distorted the nylon washer. What do you think about a different type of washer? I didn't feel like I could crank that down tight enough to make me happy?

Eric, you should probably go get a new washer. It should be tight. Don't use it if it doesn't seem right or you will just end up with water in your oil and spending $30 on more oil. I think it is recommended to change washers every time it is apart.
My leak was caused by the input shaft seal. It was being pushed out hitting the yoke and trashing the seal. I have a XR upper. Do you have the IMCO upper? Merc. had a problem with the seal being pushed out, so their fix was a newly designed seal retainer. I hope it is fixed now. I should know in a couple of weeks.
