Hello,
2006 XLV Indmar 350

After about 10-15 min on the water the engine tends to get stuck at a high RPM. When I switch back to neutral, like when pulling up next to a surfer, the boat diles at a high RPM. Then when I go back in gear the transmission slams into gear due to the RPM. I have cleaned the throttle piston but that doesnt seem to help. Any suggestions? thanks
