Port raw water pump bearings failed. Rebuilt with mercruiser bearing and shaft and seal kit. New impeller.
Port water pressure at idle 1.0 psi
Stbd 2.6 psi
Port at 1000 rpm 1.8 psi
Stbd 4.8 psi
Port at 1500 rpm 5.2 psi
Stbd 8.6 psi
Coolant temp once stabilised 160 degrees both engines through rev ranges.
Do I have a pressure sensor problem or a worn out raw water pump casing? Pumps have 300 hrs on them.
Additionally , where the heck are the water pressure sensors? They are not on the pumps.
