The boat came with a manual vacuum pump where you insert a tiny (about 3/16") hose through the dipstick hole and stroke for an eternity. I'm never satisfied that I got all the old oil out as the drain hose is quite stiff with a perpetual curl in it and I doubt that the end of it ever really touches the bottom of the pan. Other than draining the oil directly into the bilge and pumping it from there does anyone have any suggestions for a more efficient and cleaner method to extract the used oil. There's gotta be a better way!
I replaced the installed brass hand pump on my Atomic 4 (which worked but one needed a hundred strokes or so for an oil change) for a permanently installed electric pum. Now changing the oil means pushing a button and seeing the oil being pumped into the container.
But of course you still want to warm it up.
