    Default Mercruiser distributer sensor 100 ohm test

    Sensor test dosnt work by the book.Unplug the two sensor wires from the sensor ,and anything less than 100 ohms between the two sensor leads and the sensor needs replacement. All i got was range error on the multimeter ,tried differant ranges but no results.This all came about when i was out 10 miles on the ocean and the motor just died twice in a row .I got it running and got back to the dock .I checked the kill switch lead .Tried wiggling wires while running (nothing).Then my service manuall had this sensor test,but it didn't work. 2001 5.7 carburated mercruiser.

    Default Distributor cap corrosion

    My distributor cap has green corrosion on all terminals.Can you clean them with fine sand paper or replace cap? Would this cause intermittant engine stall that i had last time i was on the ocean? 2001 mercruiser 5.7 carburated. Much appreciated.

    Cap, rotor, and spark plugs are maintenance items called a tuneup. REPLACE them, and yes they will cause your miss.
