cheers.

i pulled the nipple on the shaft housing out & it was white grease that was inthere, i blew it out & put it back on with the tubing. got the engine on & all trimmed up, just need to finish off the radio box & it's set. what oil should i use? i have a access to a tube of marine grease, but jmshark said not to grease it.

i have a tub of castor oil i use to mix fuels, will that be OK or should i use light machine oil?
