2008 RXT-X Slow top Speed
The top speed is only 62 MPH. Shouldn't it be closer to 70? I had another one of these skis a couple years ago and it topped out at 68.
The Max RPM is 8140. Is there anything except the impeller that could cause this.
Any Ideas, John

Wear ring to impellor clearance or damaged impellor.

A damaged or worn wear ring will cost you speed. The wear ring and impeller would be the first things I would check based on what you listed.

Wear ring to impeller clearance to high equals loss of thrust and speed and accel.

How are you measuring your speed?
Your rpms sound fine.

I guess I am going to order a new Impeller and Wear Ring. The chart that I have says that the 2008 RXT-X should use a 14/19 Solas Concord. It says 15/21 for the 2009 RXT-X 260. Everywhere I read people seem to be using 15/21 or 15/22. My ski is stock and I do not plan on any Major Mods. Would I be OK with a 15/21. In the end I hope to get near 70 MPH.
Thanks for any advice, John

I have a stock 08 RXT 215 and it runs 66 MPH on GPS. Before buying a new impeller, you might check it out. You might be able to just replace the wear ring and have the impeller blades pitch reset.
