I have a crank from a 1989 Mercury 90. Does it interchange with the other 3 cylinders (75-115-125)? If someone has access to Merc part #'s, please let me know if they are the same. Thanks!!

You can check the part #s yourself at www.mercruiserparts.com They have outboard merc parts too.

Thanks for the link. It was an interesting site, but seemed more geared towards older Mercs. I didn't see any 3 cylinder 90's on their list. Any Mercsperts out there?

Fouled, I do believe that crank fits the 75, 80, and the 90........100 an 115 are 4 cyl motors....

D'oh! Guess it won't work in the bigger ones then. Thanks for the info!
