Thought I'd toss this out to you folks. I have a Westerbeke 21 in my boat Renegade and the transmission is grinding. I've been looking around online for information, but there's not a lot out there. I'd like to get hold of a manual and parts and/or a rebuild kit. Unfortunately, the tag on the transmission is so worn I can't read the make...looks like "Owie" (as in 'Owee, this is going to cost a few boat-units') with an umlaut over the "O". A little luck and it'll just be the thrust bearing...but my luck has been in the toilet this year (just got in the water last week!)

any help would be appreciated greatly

I think that's a Hurth gearbox. Try Westerbeke or Hansen Marine in Marblehead.
