496 mag, double beep alarm every 60 seconds. Code 37 sea pump pressure low.

Not sure what the elaboration was but the sensor cap can also be a problem. The wiring in it is weak and an open/broken/intermittent wire results in a stuck high sea pump pressure reading. You can check this using a multi-meter at the computer end of the wiring harness.

I have 2 new sensors and plan to install both today and see if this corrects both sides, and they read the same then.
His elaboration was the hose from pump to outdrive was swolen on the inside. But my boat is flowing good water and not over heating, and the sesors are reading funny so I think its a sensors issue.

Not the pump to outdrive hose. The hose from inner transom assy to gimbal housing. See pic item # 15,16 & 20, the hose will be swollen before the insert. It will allow enough water flow to cool temporarily but will quickly set the low pressure alert.

I replaced all my hoses and ti was surprised how small the the water passage gets by the time you put the plastic inserts in, ends up about half inch bore.

I appropriate al help and ideas for sure.
But i think and hope its just a sensor problem, considering I am showing 37psi, and good cooling just have a intermittent code pop up. If there was a blockage, I would think the PSI would be a solid problem. not sometimes only.

Replaced both, and rescanned without them running.
Starboard read 0.3 psi sitting steady
Port read 40-43 psi. bouncing... With it not running.
Replaced both with new.
Both read 0.7 psi not running, and sitting steady.
If you un plug them the reading rolls up over the coarse of 3-5 seconds to 43.4 then sits steady unplugged
Test drive Saturday for a 60 mile run.

It's easy for one of the two wires in the cap that plugs into the sensor to seperate and lose electrical connection or have intermittent connection, especially when running. It will then throw a highpressure alarm, the same as an unplugged condition. I've seen it happen on at least two 496's.You end up needing to splice in a new sensor cap at the pump end of the harness.
