Hey all, what’s the trick to using the Mercury oil drain hand pump to extract engine oil from the 4.5? Just tried using the one I purchased and shredded the gasket inside the pump, it never even offered to start pulling fluid. I also don’t see anything in the instructions about priming the pump in any way. Watching the Mercury YouTube video for doing an oil change just said to loosen the oil filter, remove the dipstick, and attach the pump to start pumping. Nope. Any thoughts? Did I just get a bum pump? I have the 802889A1 model pump. Is there something else I should use?
