Also need to replace the rear oil seal on one of my CR2 trannys. Where did y'all find a new seal? Jim

30wt oil may have "friction modifiers" in it, and that wont work well with the clutch.

I use synthetic because I want better bearing lubrication. The clutches work as they should.

At the upper R.H. corner of these pages you will see a button "LIBRARY"
Click it and scroll through the pages. I thin 3 or 3 back there are several manuals for gears. Whether they are for your units or not I don't know. Check them out.

@dvarholy Great idea! Thanks.
@C lectric Thanks for the link. I actually do have the original service manual. I think I more or less get the process, I'm just worried about anything I might not be aware of regarding the boat being in the water while doing the seal. I've never decoupled a shaft and want to make sure I don't wrench on something that could let water in.

changing velvet drive rear seal in the water
My mechanic pulled - just the reduction gear. It only weighs 50# and only needs a couple of inches of clearance from the prop shaft flange to clear the reduction gear spline.
He says this approach is much easier - and faster: $$$ - than taking out and replacing the seal when you cannot position yourself to the rear of the transmission because of a bulkhead.
In the process, he also discovered rust on the rear bearing that would have been missed if the seal were simply removed and replaced.
A second thought. I bought a fiber optic camera attachment from Amazon that wifi's to my iphone. I use it to look at anything that I can't get into position to see on my RV, my boat, etc. That's how I verified my tranny leak was coming from the rear seal. I plan to check out accessible parts of the transmission, while the reduction gear is off, to see if I have rust anywhere else in the tranny. With the boat in the water, there are many important things I cannot see without the fiber optic camera.
