Mercury 500 EFI Water Pressure sending unit
I have a Mercury 500 EFI with an electric Water Pressure gauge that isnt working I'm assuming there is a water pressure sender somewhere on the engine where is it located and if anyone has the part number to buy one it would be appreciated i found part number: 805605A 1 but not sure if that is the water pressure sensor listed as block pressure Thanks in advance!
