Here is my problem, hoping someone with more knowledge can help me, boat starts fine, runs good, but won't go past 5K rpm, so i can get to 30-35MPH, boat supposed to do 50, and run up to 6K, changed plugs and filters, boat accelerates great up to 5K, and throttle is a bit more then half way, when you throttle it full, it bogs down and loses RPM, back off a bit and i hear the motor rev higher( to 5K) nothing past that!
Anyone please! any suggestions?
