I just got a FX1 that is 100% stock. I am wondering what pump is the best to put on this ski. I have heard that there is Kawasaki 650 pump, a Yamaha 650 pump, and a 144mm pump, exe. I am wondering exactly what pump is the best to use (make, model, exe). I am also wondering what parts are needed to do this conversion.

If anyone has any exp. in this let me know.


Thanks,

You have two options for pumps. The kawi 650 pump which is a 140mm pump or a yamaha 144mm pump. The kawi pump mod u will need a 900zxi driveshaft and support bracket for the driveshaft. Both will require grinding on the hull to get the pumps in there. I'm putting a 144mm pump in mine, some say the kawi pump is an easier mod than the yamaha pump but idk. I personally couldn't see puttin a kawi pump in an fx1.

Yep, those are your two main options. Motoman is very anti Kawi pump. I went the Kawi route myself. IMO the Kawi pump is more affordable, easier/less expensive to replace parts if anything breaks/wears down the road, and takes a little less grinding on the hull (pump shoe area). You can also use the X-2 trim if you go the Kawi route.

Either one will make a huge improvement over the stock pump and it really comes down to preference.

I did a write up when I was doing my swap, it's in this section somewhere.

Hey moto... I know Yamaha makes a 155 pump...

Reasons you couldn't/wouldn't use the 155?.?.?.?

Judging by the size of the pump, it would be a PITA to fit it in the FX cavity without major hull work

I figured that.... but that doesn't seem like anything that people around here would shy away from.

I just wonder.... enough power to load the 155? If so... you would be moving a LOT of water for a standup.... That is where the thought began. I can't imagine that the members of this forum would be afraid to attempt such a build if it reaped large enough benefits.

The 155 would be overkill. Plus they're fvckin' pricey. Not too mention it is way too big under there. You would have to fab up a rideplate like J said. The 140 or 144 is plenty sufficient. If anything get a skat magnum pump

Thanks for all the info. That is what I was looking for.
