    RPM's VS. SPEED?

    ski is an SUV only touching on 40 mph...Done a bunch of searches and it looks like my rpms are correct(or at least very close) I would of said they are just under 7k..so 6850....If my rpms are correct, the only thing it can be is pump, correct?.when I say pump i'm meaning wear ring and impeller....they look pretty good but this must be it, no? nothing hanging down to cause drag

    Is this GPS speed? If so it is low. Yes your rpm's are not bad. The ski should top @ about 48 to 50, remember, it is an SUV. Good Luck
