2006 Sporster 215 4-Tec Low Power
First time out this year... Starts and idles, runs slow ok but when throttle is increased...no power and rough. Assume it was limp mode, not sure. Then when restarted, one long tone and check engine light. Read code P0520, cleared history, replaced oil pressure switch. Restarted, no beep or check engine light but still no power.
Only use boat 1-2 hours per year. New battery, plugs fairly new, look good, oil on dipstick looks good, coolant was low in bottle so I put some in, back flushed the exhaust cooling, pulled exhaust and air intake hoses off to check for obstructions, pulled the jet pump off--looked fine, impeller turns. Changed fuel filters, not fun, dirty but not too terrible. Changed oil/filter, cold, just under 3 liters, looked ok.
Anything else anyone can think of? Is it possible the oil pressure switch code was pointing to oil pressure issue not just the switch? Assume if was in limp mode, that it clears itself, no procedure?
Can a clogged fuel filter cause this kind of lack of power. Wouldnt I see a check engine for fuel mixture? Maybe something in the pump I am not seeing. Just dawned on me that I didn't rev it up in neutral in the water. I'll try that too. Not optimistic. Any assistance would be appreciated.
