Hi,
I like to share
some test data with you.
I ran a test with a
small (less than 20 LBS) , cheap electric
outboard.
Propeller runs in
air.RPM in water will be less.
Silicone DOT 5
brake fluid: Thruster runs but at just 1600 RPM. Fluid is not aggressive but
the higher viscosity (it is still thin oil!) make it run slow. I can not
grab thin silicone oil .
WD 40 : thrusters
runs 3550 RPM
Empty Thruster:
runs at 4050 RPM. Thruster had contained WD40 but the brush fire caused no
explosion/fire
So if the WD 40
don?t dissolves the plastics over the years, I am happy with
that!
Met vriendelijke
groet, Emile
