Re: drive oil in raw water exhaust

I pressure checked my mc-1 drive in two pieces. Determined that the lower was holding pressure. However all the seals in the upper were trashed. Ya need to find out which seals are bad.

The main one that looked the nastiest was the lower oil seal where the lower drive shaft mates with the upper. I had clean gear oil in my raw water exauat as well.

Also my yoke seal and seal surface on the yoke are in need of replacement.
