View Full Version : Low oil presure at idle

07-03-2011, 01:26 PM
I have an 02 X30 with the 330 EFI. Yesterday as the boat warmed up to about 160 (according to the gage) my oil presure gauge would flat line and the alarm would sound. If I boost the rmp to 600, the gauge would jump to just under 20 psi. At cruise it runs 40 -50 psi. What's up with this? Is there a problem?

I would change the sending unit first. Mine did simular to that. and a new sending unit fixed it. skidim.com has them

Thanks..I have another question. I changed the oil and filter but couldn't readily fine 15W40 oil, so I filled the 330 EFI with 20W40. Is ther something soecial about using only 15W40?
