  • 02 Ultra 130di bogs down/won't get over 5mph or 2000rpm

    I rebuilt my Ultra 130di with SBT parts, put it back together, and started it up in my driveway. It ran like a top and would get up to 4-5000 rpms. When I put it in the water it starts and runs, but it will only go about 5mph and the rpms go down to about 2000 max. All 3 cylinders have 125-130 psi and I can't figure out what's going on. Could it be the jet pump/impeller? Please help me figure this out!!

    You should still get good rpms out of the engine if the jet pump has issues so I dont think thats it, With the D.I ski it could be many different things your best bet is to bring it to Kawi and have it checked out on the computer.
