I have solenoids that need replacing on my K-Planes pumps. I pulled one of the old ones and it was manufactred by Phelon and has a part number stamped on the metal bracket - 31-101746. I could not find this part on the net so I took it to NAPA. NAPA could not cross reference the number but found a soleniod that looked like it - NAPA ST81. I installed the new part and got nothing , no click, nada. I reinstalled the old and got the click. Does anyone have a manufacturer/part number that will work? Attached pic is what they look like. Boat is an '86 so I don't know how old the current solenoids are.

Thanks,

Ron

call mercury or look it up online.

Lets just do it the easy way. What year and what series tabs do you have? There are about 4 different relays that will work if the mounting locations line up.

I think I found my answer. NAPA sold me an automotive unit, grounded to the mounting bracket. I needed an isolated ground model.

Thanks for the replys,

Ron
