View Full Version : Oil Pressure

Ok...I got my boat back from winterization and now I'm seeing wierd readings on my oil pressure gauge. At idle, the needle is crazy (swings really fast from about 20 - 80psi). When cruising, it's buried at 80psi (which is max). Should I be concerned about my engine or is my gauge on the fritz?

Of course the boat ran nearly perfect all 4th of July weekend...which was alot!

Same issue here. The gauge finally settled at 55-60psi later in the day. It ran great all weekend otherwise.

Mine used to do that and when I pointed it out to my dealer they suggested a new oil pressure sender. They replaced the sender and has been working properly ever since.

Agreed, sounds like an oil pressure sending unit. You can spring for the "marine" one, but I doubt they are any different than what you can get at your local parts store.

That is exactly what my dealer told me....sending unit. They're pricing me one right now.
