Re: [electricboats] Thunderstruck Chain Coupler Grease

You have to paint the pulley sprockets with a rust preventer. For the chain coupler your need to use some kind of rust preventing lubricant - the others here have given good suggestions - I used lithium grease. 

But… I also found I had to place a plastic box to go around it and rotate with the shaft because otherwise the grease ended up everywhere. I used an outdoor electrical outlet box because it had perfectly sized knockouts on each end. It seals well and keeps the water out.

You gave some pretty solid clues for me to do a web search.
