warning alarm and pressure sensor

[echo007]

Had a engine warning alarm go off on my mercurser 6.2 liter MPI in a 2003 Rinker Fiesta Vee 270, enime running at @3200 RPM at the time. Computer check of codes indicated bad water pressure sensor. Sensor replaced with no luck. Suggestion of replacing the impeller. Any other ideas?

Well,..........<br /><br />It Sounds like the "bad water pressure sensor" was doing it's Job,+ If you do in fact have Low Water Pressure,.........<br />The Impeller would definitely be the 1st place to Look.........<br /><br />When was it last changed,..???<br />Do you boat in Sandy water,..???<br /><br />Good Luck,+ Welcome to the forums here at iboats.com..........

Re: warning alarm and pressure sensor

What was the exact Fault Code?<br /><br />Sea Pump PSI Lo - Does not indicate a bad sensor, only no system pressure<br /><br />Sea Pump CKT Hi - Indicates Open circuit - 0 PSI<br /><br />Sea Pump CKT Lo = Indicates voltage high or short<br /><br />If replacing the sensor did not correct the problem, and you still have a Sea Pump CKT Hi or Lo Fault, the problem may be in the wire / wire connectors between the sensor and ECM. It you have a Sea Pump PSI Lo, then impellor, pump, inlets, etc are the place to look.<br /><br />Dave
