2007 RXP Acceleration Problem

[cbuckham]

I have a 2007 Rxp 215 with a stage one riva kit on it. All of the sudden when I start to accelerate off of idle the engine just revs. You can baby it up to plane and once you are on plane it is fine. Impeller and wear ring are fine nothing wrapped up. Having issues determining what actually is problem anything will help.

Just checking I had same problem, and from looking thru to impeller every thing seemed fine , but when I took it out and examined backside of impeller had 3 of 4 blades destroyed. MAYBE

99% chance it is your jetpump, more likely wear ring

The wear ring is fine. I have a solas 14/19 pitched prop looks perfect but have not taken it out to look at back side yet.
