I just noticed that I've got a fair amount of oil in my bilge. Motor is an HP500 EFI. I've checked all the valve covers and everything obvious on top of the motor and can't find anything. The front of the motor and water pump area are dry. I can't see for sure but it seems like its coming from somewhere towards the back/center of the motor? I've stuck my hand down all around the sides as far as I can reach but everything is dry. Its definitely motor oil and not drive or trim oil. Anyone have any suggestions of where to start looking? Oil pressure sensor? I'm reading good oil pressure so not sure if that would still be the case if it were leaking. Any hlp would be greatly appreciated.

06-03-2013 12:43 PMI tried looking around the oil cooler but didn't see or feel anything there and nothing on the lines from the filter. The boat sat all winter without any leaks - I completely cleaned out the bilge and would have seen anything dripping. Seems to have started once I started running the boat?

Sure its engine oil?
I have heard a lot of folks having trim or tab pump reservoirs mounted on seat back in front of motor, those leak and oil gets drawn in and tossed around by the belts/pulleys/airflow around them.
Just a thought...

I had a leak that I thought was a fitting for an oil cooler and it was the distributor gasket. It would burp a little and it would run down the back.

06-05-2013 09:51 PMDon't forget, most use engine oil in the trim pumps....

I think that it was a guess.

Possible, but I was thinking that if a guy has the benefit of being with the boat, and seeing, touching and smelling the oil in question, I'll give him the benefit of the doubt.
Post number 1: Its definitely motor oil and not drive or trim oil.

07-04-2013 09:20 AMNo still haven't found it. Checked all y suggestions here but can't find anything. Almost seems like its coming from somewhere in the center if the motor yet the oil pan appears dry? I'm wondering if it could be a drain plug. For now I've got oil pads down to catch any drips. Might have yo wait til Fall and pull the motor to get a better look.
