I probably have 40 hours on the boat now, what gives? Is this the sign of a BIG problem??

Wow, either something clogging the pump inlet or the impeller wear ring is gone already. Check for weeds, plastic bags, ski rope, etc. in the intake grate under the boat. Where do you boat? Fresh or salt?I have not been able to get my Challenger 180 over 30 mph (speedometer shows up to 70) however, I am at 7.5 - 8 RPMs when I reach 30.

Take a really close look at the pump intake and the area between the impeller and stator vanes. You probably have some weeds stuck in there (or something else). If nothing is stuck there, check out the surfaces on your impeller and the wear ring (is it scratched and/or dinged up?). Most likely it's not a major problem. Any disturbance in the water flow will really mess up performance.I boat in salt water.
