Default yamaha oil pressure to high?

All, I need some help.

2007yamaha f150

Here's the story..... last august while on rainy lake I hit some rocks. New lower unit and prop was covered by insurance. Got the boat back and only used one time in the fall. Used the big engine for a but 1 minute as all of my fishing was done by using kicker. Seemed to run fine with no issues. I usually don't winterize since I use it most months fishing the river. This year I didn't use it until April 6 for the first real time since the accident. It seemed to run fine. I did notice that the oil pressure gauge was pinned past the upper highest level of 30 and would only move a little higher as the rpm increased. Is will not move even if the engine is turned off. I have to admit I have never paid much if any attention to this gague before. I did now because of the rock incident and I was curious to see if everything was running OK. Oil looked good. Oil level was good. No alarm came on. I am going to do my annual oil and filter change before the next outing.

Is this normal? Am I over thinking something or do I have an underlying issues?

Your thoughts are appreciated.
Thanks,
Matt

Oil pressure sensors do fail. I've replaced a couple in vehicles. Gauge may be bad as well. Neither should be too expensive, even at a dealership.

Maybe try disconnecting the gauge and see if it returns to zero .

If the motor stalled when you hit the rocks ,it may have damaged the fiber gears in the harmonic balancer causing oil galleys to plug . End results are not good .

To check your oil pressure, unscrew the oil pressure sensor and screw in a manual oil gauge with pressure tube.

Go ahead and run your engine.

You will instantly know the correct number of oil pressure that is being generated by your engine.

Then you can make an educated decision on whether you have internal damage, or if you have a gauge sending unit problem.

The engine never stalled on impact. I shut it off seconds after impact and realizing I was OK.

Thanks REW. I figured you would have some knowledgeable advice!!!!

Anyone know the complexity of removing the oil pressure sensor on these engines? I am far from a mechanic, but can follow directions. If it is to much of a pain I will have to pay someone to do it.


Thanks,
Matt

I talked to Yamaha today and they gave me the following information.

On your engine, when the engine is well warmed up and running wide open, the oil pressure is normally at 55-60 psi.

When the engine is warmed up and at idle, the oil pressure will be 30-35 psi.

When the engine is cold and at idle, the oil is thicker and will run at 40-45 psi.

Good luck

Thanks a ton REW!!!!!

Maybe the gague and motor are just fine and I was over thinking things.

Anyways, the repair place agreed to take a look at it free of charge. I'll make sure and post the results.
