[Fr. Frank]

Don't use Anti-seize in saltwater. Not only does it accelerate electrolysis, it also turns from an anti-seizing compound to a permanent epoxy over time and with the application of electricity. Working in marinas we saw it repeatedly with people who used it on propeller shafts, and then didn't remove and lube the hub for a couple of years. We would have to burn the rubber hub with a torch to get the prop off the hub, and then sometimes even have to split the brass hub with a die-grinder to get it off.

Lube the bolts (and the propeller shaft) with a marine-grade grease, preferably lithium grease or molybdenum-sulfide grease. Lithium based grease is usually white or light yellow in color. Molybdenum-sulfide is usually bright red or bright blue. Don't use any grease with graphite. In saltwater, graphite grease clumps and hardens.

I use CRC or Pennzoil brand lithium marine grease for bolts, props, and axle bearings. I also spray my whole powerhead and tiller arm with Fluid Film after rinsing the motor post usage.
