97 Challenger Impeller Question

[dbarron709]

Hi Everyone, First, can't say how much I appreciate this forum... it has been extremely helpful and education. Today's question:

I removed the impeller from my new to me challenger and the seadoo part number is 217000821. I looked it up and it says the pitch on that impeller is 11-22. In the manual it says the 97 Challenger had PN 270 000 620 with pitch of 11-25.

How will this difference in pitch affect the boat?

Thanks.

I don't think it is a huge difference, try and run it and see how it performs, if you don't have a tachometer get a tiny tach or similar device to monitor rpms.
