No question the best impeller lubricant is beef fat tallow.




No, wait, I meant food-grade silicone oil or grease. Johnson puts the stuff up in little tubelets and sells them along with their impellers. You can buy some yourself..

Don't think you really have to worry about it, if before you start your engine you detach the raw water hose and shove a garden hose in it and clamp it shut, turn the water supply on untill water comes out the exhaust, there should be enough water to lube the impeller, no dry starts.

100% food grade silicone spray avalable at dive stores

Food grade silicon spray.

Use it to lubricate the impeller.

I also use it as a rust-preventative storage coating on the engine blocks of all my toys.

Silicone or water based sex lube, anyone?

How hard can anyone make out something so simple. Any lubricant, KY, Vasoline, grease, motor oil, cooking spray, spray silicone, Go-JO, chicken fat, 303, ArmorAll, hog lard, Crisco, whatever, will be washed away within minutes after the boat is cranked and the pump is working. All you are using a lubricant for is to help get the impeller installed and buttoned up to use, then the water does the lubricating after that. I have always rubbed a light coat of Lubrimatic Marine Corrosion Control and Wheel Bearing Grease prior to installing or if in the middle of the lake, on my boat or someone elses, Go-Jo in a small, small baby food jar that I also use to clean up my hands after the operation.

There have been many times where I've gotten my boat ready late at night on some weeknight in the garage.....reinstalled hoses, impeller, battery, prop, etc but the boat may sit for up to a week before putting the fake a lake on it and turning the key. You're correct in that if you are going to install your impeller and then start your boat in the water soon after, it is a "don't care" on the lube.

I have always rubbed Lubrimatic Anti-Corrosion Wheel Bearing grease prior to installing.I don't completely disagree - but it's true that after changing the impeller with the system drained of water, that first start at the beginning of the season is likely to be a dry start. Nice to have some persistent lube on it for that first start.

Anyway, the petroleum-damaging-rubber concept is perhaps more meaningful relative to MasterCraft's recommendations that the impeller be removed at the end of each season, lubed with vasoline, and stored in a plastic bag for the off-season. Vasoline can damage rubber, so personally, I'm a big fan of food grade silicone, which can't.
