Low oil pressure! locked computer

[Robby]

03 210 SAN

Yesterday I put the boat in and after riding around for about 30 minutes on a new oil change the computer limited my RPM (limp mode). I pulled the dipstick and there wasn't anything showing up. Originally, I put 5 1/2 quarts in on the new change. So we added some oil and then tried to restart. The motor would start and sounds fine but the computer didn't allow me to bring the boat on plane. Have I locked the computer as a result of the original low pressure reading?

Currently, on 15-40 amsoil @ 800 RPM I'm reading about 37 -40 psi. Is this correct?

Any idea on what could be going on?

Thanks Robby

I don't have that new of a boat, but try unhooking your positive battery cable and rehooking it back up. That might reset the computer????

My understanding is that this boat won't reset without the "brain" at the dealership. I had a knock sensor problem in the past and I had to take it in to reset the computer.

There is a tool available, typically at a dealership, which is a code reader.
Also known as a "winky blinky," this tool is used to erase codes and get you
out of gaurdian mode. It involves installing the tool to the data link connector,
turning it on, messing with the throttle, thus erasing the code. I suspect that
the code thrown is your problem.

You might be able to make your own "winky blinky." Try calling PCM for
some quick technical advice. 803 345 1337.

Just thinking now.............did your check engine light come on when you were running it? Did your gauge on the left flash "Low Oil Pressure....see dealer?" It's possible that you did NOT throw a code, but perhaps have a bad oil pressure switch. You can test this by running the boat at idle and disconnecting the lead wire going to the oil pressure switch. If the check engine light goes out, then you've found your problem. R/R the switch and you'll be back in business.

Sorry to ramble.

I did get the flashing "low oil pressure ... see dealer" signal on the left gauge and the check engine light is on. I'll try the oil pressure switch this evening.

Thanks Rob
