I Own a 2006 Baja w/twin 496HO's. Previous owner installed smartcraft systemview.
I noticed the port engine is about double what the stardboard engine reads.
eg.
Idle port is 3 PSI...Stbd is 6 PSI
3500 Port is 10 PSI....stbd is 20 PSI
Depending on where the sensor is located I am thinking either one is good.
Low PSI could mean a bladed or two is missing and its having a hard time sucking.
High PSI could be somthing is plugged farther down the line and its reading high pressure.
not getting a code= displays reads good when running....Just feel its a big difference in pressures.

3 psi does sound very low to me .
i would change the impeller's just for safty reson's they should be changed every year or two depending on use of boat .
just my 2 cent's

typically they range between3 and 5 p.s.i at idle. and depending on application they run between 25 and 30 p.s.i .
obstruction does raise pressure, usually debri stuck in the oil cooler and p/s cooler.

Try swapping the two water pressure sensors and see if the pressures remain the same or flip close to what they are now. We've seen a lot of range in these sensors and it seems to be sensor calibration issues more than water pressure issues.

Will the real water pressure show itself?
