What is the best after run oil to use

[dr gary turner]

Motors without silicone ramp, flush with WD-40 and then use Corrosion X. Best in my years. Of boating. Bill McGraw put us onto Corrosion X. It will prolong the life of your bearings .

When I played with nitros it was mandatory to flush with WD-40 to get water out then flood with Marvel Mystery oil!!! That's how Daddy wanted done and I never changed?? Thank God for Gas Boats!!!

Everybody has there favorite. Mine is outboard fogging oil. Protecting bearings is what its made for. It also foams up and coats everything, and does not require re oiling every couple of months like some other options.

I have been doing the same for the last few years.

The only problem with using Marvel Mystery oil is it will eventually leave a varnish you can actually use that as a form of loctite it will not leave a residue on the threads like regular lactite does. John Equi showed me this trick over 20 years ago.

Guys, this is all good advice for the after run oil...just don't use any WD40 in your Nova motors with the silicon ramp! I use Corrison X and it work great to get the water out and keep things shiny inside.

if your running alky and oil thru motor to flush it you still need to remove the alcohol from the motor, alcohol absorbs moisture and over time will kill the bearings and can corrode aluminum.

I think one of the most important things you can do is disconnect the fuel line and put the glow plug ignitor on a plug and turn the motor over to make sure all the fuel is burned out of it.Keep turning it over until it won't pop anymore. I use JB 80 as afterrun oil because it has a foaming action that really gets into the bearings. I also leave an old plug loosely in the motor when I shoot the afterun oil in as this will cause pressure in the crankcast force the oil into the bearings.

X2, always run the engine and disconnect the fuel line to run the nitro out. Then flush as above.
