    Block/Crankcase Interchangeability?

    I'm in need of a good used set of cases for my ski. Anyone know which year/model crankcases are interchangeable? I know the 04/05 blocks are the same and the 06+ cases will also work. How about the earlier 02/03 155 hp cases? Are they all the same?

    I personally would never mix and match cank cases. Give it a try, make sure to Mic the mains and that they are round.

    155 cases are the same as yours 04 RXP.If you get some 06 and up you can use them but you have to fit the oil valve which 06 models dont have.Crankcases come in pairs dont mix em up....

    Thanks, thats what I thought. Part numbers are the same. And I've been around long enough to know you dont mix them up, as far as upper and lower cases go.

    I am not aware of any differences between the 02-05 cases.

    Funny, you said you need a "set" and yet almost everyone gets the idea that you are planning to mix them up for some reason.
