2003 Sportster rev 4000RPMS in water, out of water will only rev 6500RPMS. Took jet pump off so no resistance still 6500RPMS. Checked fuel pressure right on per manual. Any advice?
I just purchased a 2003 Seadoo Sportster 4-TEC took it to the lake today and it will only turn 4000RPMS. Starts fine no beeps no other known issues. Any advice what to check?
Thanks Chris
