With this gearbox. the noise is not bad at all. I have mine packed...and i mean packed (7 ot 8 ounces)- with "Green Grease" a very sticky, stringy marine grade grease. Makes all the difference. The plunger is a chrome tire pump with a plunger (hardware store knob on a brass tire stem with threads to fit the knob) attached to mimic the look of an early oil pump.
