Re: Flushing Gear Housing

[Tubs]

While 105 may not specified for you motor
it is used as a gear lube in many outboard
motors. Kerosene isn’t. To get the 105 out
all you need to do is warm up the gear case
with a heat gun. (not a torch) The 105 will run
right out. If you still feel the need to flush,
fill it with gear oil, run it a bit and drain.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
