Hi:
I pulled the prop off of this motor that I bought a couple of months ago and found a bunch of mono behind the prop. Pulled the lower unit drain plug and yep, there is a little water in the lube. Are there any special tools required to change that seal? Is there a web site somewhere that shows you how to do that. I have a shop manual on order, but it has been back ordered for weeks.

Thanks in advance for any help you can provide.
