1995 seadoo speedster manifold

[iamgretzky]

I have a 1995 seadoo speedster and would like to change an exhaust manifold. Can anyone tell me if different years or numbers are interchangeable? IE: 657 587 721 etc. Mine has a number stamped on it. Also can one from a jetski not a boat be used?

There are differences in them in the cooling iirc. What is the part# on yours?

The boat is at my brothers. He took it apart for me. I'll check the numbers and reply again. Thanks

What your looking for in a replacement is pn#290979141, that was the last manifold made for the X series of the 657 engine and will bolt right up to your cylinders.
