Reply To: Johnson TS20 lower unit grease

[aquasonic]

The TS-20 model does have seals, and can use grease or 90W hypoid oil. For 90W the best way is to buy an inexpensive pump that has a hose that screws into the filler port. The pump screws onto the top of a quart or gallon jug of marine grade 90W taking the place of the cap. Once hooked up, just pump the oil until it runs out of the open top vent. Replace the top vent screw before disconnecting the filler at the bottom. Then disconnect the filler fitting, and quickly screw in the drain plug before much oil leaks out.
