Re: Mercury Mark 5

Great little outboard! Look by the prop & you will see two small filler plugs. Behind the plugs are gears & shafts to supply the power made to the prop for power. The driveshaft from the motor it’self goes down to the gears so the prop shaft will turn in a horizontal rotation. Check the gears & shafts cavity for grease by opening the filler plugs & let it drain into a clean glass jar for 24 hours, Then refill from the bottom filler plug until the lube comes out the top filler plug.
Will someone help him with the best lube to use? I use the tractor grease but can’t remember the name of it. Been out of the loop from illness so help him please.
Good luck, great fishing motor. I own a Mercury KF5 which is an earlier model of the 5hp twin cylinder, fun little motors!
