03 Sportster with max 5500RPM
Posted 02 September 2008 - 02:01 PM
can anyone help explain why my 03 Sporters 130HP will only rev to 5500 max with no vibration and therefore will only do 15 to 20 mph. Does my jet pump need to be cleaned for depbri and if so can this be done by myself.
Thanx in advance.

Have you checked your impeller and wear rings? You could be experiencing cavitation.
If it never gets above 5,000 RPM or so then you could have a fuel starvation problem. Does it ever rev above that? What kind of beeps are you getting if any? Does it smoke normally? I take it you have the carb 947 being a 2003.

I'm new to the Sportster boat. I have been working on mine for 2 weeks and went out for a sea trial today. Could only get 4500 RPM's, One plug was wet & oily, checked further and found that the plug wire was faulty. Corrected it and now get 7200 RPM's, different boat!!
