I thought I would conclude this thread with my findings. It appears that the HP output of a pump is affected by many things including diameter and impeller pitch (which probably isn’t a big surprise to anyone). The RFIs have the 140mm “Big Hub” pump which will affect how much water flows through...

I did do some research and noticed that they are different pumps. The reason for my concern is it seems that the bigger the engine, the greater the Pump Output Rating is. For instance, the 1997 GSX 800 is rated at 56HP, the 1999 GSX Limited is rated at 71.1HP and the 1999 GSX RFI is rated at...

Thanks. Is the Pump Output rating the same as Crankshaft HP rating? If so, I'm wondering if the difference in ratings is due to the added electrical strain on the engine from the RFI system. I used to work with the electrical systems of cars so the complexity of the RFI system doesn't scare...

I have done more research than I care to admit and I can't find what I'm looking for. I noticed that the Pump Output rating of a 1997 GSX 800 is 57HP and the Pump Output rating of the 2000 GSX RFI is 45HP (according to the Seadoo Manual). I know about the RFI issues but what I really want to...
