i start mine for a couple seconds everytime i pull it out of the water. i do it to get the water out of it. also if mine is hooked up to the hose, theres a ton of water that comes out of the pump. i am one of the crazy ones that will run it for tuning on the trailer, and i do not see how all the water coming out of the pump isnt keeping it lubed. everyone says disconnect it but i am a rebel.
