No Oil Pressure??

[seth]

I looked down at my gauges the other day while pulling a rider and noticed my oil pressure gauge was reading 0. I immediately stopped and idled back in, luckily I was close to the ramp. The engine never sounded different and seemed to be running normal (im not sure how long it was reading 0). Im wondering if my gauge is bad or has a short? If there was no oil pressure would I be able to tell right away? Any input is appreciated.

Have you checked the oil level since then

The engine would sound different for sure if you had no oil pressure. I just experienced this with my other inboard boat - an older Supra Beast - not my Nautique. As it turns I had installed the wrong type of oil filter. After about 30 hours or so with that filter I started the boat one morning and it immediately started making loud knocking and pinging sounds near the top of all 8 cylinders. You could just hear something wasn't right. If your engine sounds normal it may be something as simple as the gauge.

IMO ....if you made it back to the dock....you have oil pressure.

Check for a loose wire on the back of the gauge. I had that problem. Surely your engine would go into safe mode and alarms would go off if you lost oil pressure.
What year is your boat?

It is an 01 SAN, and as soon as I saw the gauge I turned it off and checked the oil. The oil level was fine, I have since changed the oil and filter. When I tried to remove my dash to check wires I stripped out one of the allen bolts trying to remove my steering wheel, and havent been able to check them. Thanks for the input, im thinking (and hoping) its my gauge as well.

I just had my boat in for service and they noticed my oil pressure guage was showing 0 too when the engine was running. I had no idea how long it had been showing 0. They replaced the entire guage.

Was it the gauge or sender? I know you said gauge...but...just checking.

Senders are notoriously iffy. That's what I always replace first. Usually that fixes it.

You can pry the plastic cap on the center of the steering wheel, and then you will see a 3/4 nut in the center. Remove the nut, mark the steering wheel position on the shaft, and you can pull the steering wheel without removing the six Allen screws. Glue the cap back on with an RTV sealant. (Silicone Seal)
I believe that all the motors that were available, had additional sensors that would turn on red lights, and at least put the motor into a limp mode if you truly had no oil pressure.
