I've never lubed it, but I have only put about 10 packs through the boat. I guess it's probably due. I am sure I should have done it before I ever put it in the water, chances are it wasn't done properly at the factory. The motor is a bran new trinity spec motor, I would hope it doesn't have any issues yet. I will do the brush cooling and lube the driveshaft first and see where that gets me. Thanks.
