I would have posted the correct size, but I would have had to go out to the boat, take the coupler apart and then tried different sockets until I found the right size. I also have the ZF Hurth transmission, so I couldn't guarantee it would be the same. Count me as one who looked and didn't answer.

So, for future reference: What size was the shaft nut on a 90 ProStar 190 w/ 1:1 Velvet Drive?

Glad you were able to get it worked out. It doesn't sound like it takes much bend to be out of tolerance. Here's to running smooth on July 12th!
