Good To Know

Q: Is this an original Sea-Doo part? A: No, it is an aftermarket replacement that cross-references OEM number 420241221, and it is described as for Sea-Doo watercraft. Q: How many of these should I order? A: Check your engine layout and replace as many as your power valve covers require, since each cover uses its own adjustment screw.
