High PS alarm on a/c

[Frockett]

I have a 1997 37 foot sea Ray aft cabin Can’t get water pump for a/c s to fire
I was told to check the pump relay but I can’t locate it
Any ideas

Are you not getting prime or is the pump not turning on? It's pretty common to struggle with prime at times. You can resolve this with a garden hose. Send some water through the system from the hull-side outlets and see if that fixes it.

If it's electrical.....that could be more tricky.

But pump not activating

It's called a "trigger switch" and typically located behind the electrical panel (although on your model it could be somewhere else)

Replacement switches are about $60-70. Look for the junction box for your AC units.
