bad pressure sensor or impeller? 8.1s

[sporters78]

started boat up today pumping water from both engines ,looked at the gauges for starboard side 0% psi for water pressure, rev a little goes up a bit, replaced sensor last year and impeller 150 hours ago, temps are normal. what do you think? really hard to change implellers and the sesors are a pain too
big thanks

Have checked the strainers?
150 hours seems low for impellers. But if you sucked up debris that broke up it might have damaged the impeller.

Same thing just happened to me - swapped the sensors and the "condition" swapped with it - just need to pick up a new one now.

Steve, the Starboard side isn't too too bad if you squeeze back in the bilge. I just changed my A/C pump and it was pretty uneventful.
