    Not sure rpm my 02 runs around 55mph. Doesnít have a temp gauge so not sure.

    Do you notice the pump being louder on your 2002 compared to other year models?
    i also have an 2008 and the pump is much quieter.

    I have a 13 as well I think the 02 is quieter. But I switched the 02 pump over to gear oil. That made a big difference. Switching the 13 before upcoming season.

    I might give that a try what are you running in yours and how much?

    75w140. Not sure how much. Just kinda eyeballed it. About 2/3 of the cone, maybe a little more.

    And weíre talking about noise out of the water right? In water they both make no noise.
