    Mercruiser 3.0 L oil pressure switch Question

    Took out my oil pressure switch to check it. Problem is my manual no 26 shows a test procedure for a oil pressure switch with only one terminal connection whereas my switch has a three pronged connection. Haven’t been able to find one online that matches mine. Any ideas?

    Oil Pressure sender/switch question

    This should have an easy answer. On my 2005 Mercruiser alpha one gen 2 3.0 liter engine: is the oil press sender and the oil pressure switch both contained in the same housing. In other words if I order a new sender will I also be getting the switch?

My alarm goes off intermittently while driving the boat but temp (175deg) and oil pressure (around 40psi) are normal and my gear oil; reservoir is...

    1986 75 hp Merc outboard Problem

    About to pull my hair out! I have 1986 75 hp Merc outboard. Last trip out engine seemed to run fine but after sitting awhile (fishing) and restarting the engine, it would cut off when I put it into gear. Got back to dock using my trolling motor. Figured I had a carb problem so I pulled both...

    Opening in top of engine?

    I have this opening in the top of my engine (see images) that is missing something. It has threads and I can see oil in the opening, I don't know if there is supposed to be some type of sensor or plug in the opening. I attached two pictures: one shows the front of the engine and I stuck a...
