hello, i'm not sure if this is the correct place to post/ask this, but i have a 2000 Speedster with the Mercury M2 engine and the hydro surge grate, and i'm looking to replace it. i wanted to make sure that this is the correct part number for my boat (before i drop the $$$) since most of the topics i've seen discussing this are related to other models of Sea Doos (Challenger and Islandia).
