View Full Version : High oil Pressure?

05-22-2010, 06:46 PM
I have a 2006 x-1 with the mcx. When I start the boat and the motor begins to warm up, the check engine alarm sounds. The oil pressure begins to rise drastically to almost 90 psi. the boat doesn't make it to operating temp. before I shut it off. Any ideas?

I would start by hooking up a reliable oil pressure gauge to the engine, just to verify that pressure reading you are getting. If it is indeed 90 PSI then you could have a stuck closed oil pressure relief valve in the oil pump...

def sounds like a stuck valve. have you changed oil and filter. make sure no obstructions.

How do I make sure there are no obstructions? I am changing the oil right now.

oil came out extremly slow.. is that normal? I also let it warm up to operating temp and still seamed slow.

How long/many hours since your last oil change?

about an hour ago I changed it. No difference in oil pressure, still idles at about 45psi and runs at about 60 psi. I put in exactly the 4.5 quarts that mc specifies.
