I've replaced the senders and it made no difference on the reading. Try swapping PCMs with the other engine. Have you had any remapping done on the PCMs?

Yes, It's off my scan tool. I re-checked with key on but boat off and it read 31 psi?? What would cause this? Just a bad sending unit? That explains why one reads 3 psi at idle on hose and the other 34 psi. It's actually probably the same as the other one. Still trying to figure out why my dump valve keeps blowing off? I replaced it with a new one, so I'll see what happens this weekend.
