525 efi oil pressure loss?
 

I took the boat out for the first time this year and every thing was fine for about 10 minutes than oil pressure dropped to 21 pounds and the alarms went off. Checked the oil pressure with the smartcraft scanner and it is around 22 pounds at higher rpm and around 20 at idle. Any ideas of what the problem is? Also the oil temp was around 230 with a short 80 mph pass and that seems high for such a cold day and cold lake water.

You may want to change the oil filter. Is it a Merc. oil filter?

I already dropped off at mechanics. I can't believe I didn't think of that. Have you seen that before?

Been there done that !
If your smart go down to the mechanic ASAP tell him just to change the filter do nothing else ! Start the engine Ck the preasure yourself. If its still low, oh well your in trouble.

if it is not the filter. What are you thinking? If the oil pump was out, I would assume there would be no pressure.

If it was ok when you put it away last fall and there were no other problem I would put a mechanical gauge on it and then check it. It may be possible that a sensor has gone bad and I have never seenor heard of an oil alarm going off at 21psi.Engine oil pressure in a big block after it has been run hard and the oil thins out maybe at 15psi.I think you have a sensor problem thats your trouble and a filter bad ??? its possible but I don't think so.Just my 2 cents worth. :drink:

I'm going to start with the filter. What pisses me off is that I had a extra filter in the boat with me. I'll call the mechanic monday and tell him to switch filetrs first. I think lucky is onto something. :rolleyes:

Stupid question, but you didnt have any recent fuel problems did you?? or have excessive fuel in the oil for any reason?? It may thin it out & lower pressure.. Im sure you probably would have noticed if you did.. I just figured I would mention it.. It beats pulling an engine.. :) Jamie :)
