Along comes the OP (thank you) and asks, and out pop a bunch of options for what may be a better mousetrap (thanks to all who made the suggestions). These are the things I love on this forum.

As to tube down the dipstick, or suck from the top, I've tried both, and in my sump about 1/4 of the oil gets left behind if I suck from the top. With less than a gallon in the thing that's not a lot, but at the same time I like to get as much as possible. Guess it depends on the design of the sump and the 'stick tube.

Thanks again (even if I'm not the OP) for teaching an old dog new tricks.

Great point. My suggestion would be to pull from dipstick tube until sucks dry, and then insert small tube to get more of rest. Without a drain plug at bottom of sump you'll never get it all.

I have this oil vaccum suck type. It's definitely the best I've had. I've had perm installed electrics etc, drill type (what a mess) but this type puts the oil directly in a reservoir so you don't have to make a mess transferring etc. The one I have has the pump directly on the storage reservoir, but similar to the one pictured.

I can access the drain plug on my 4JHE, and out of curiosity after sucking the oil out with a small tube down th edipstick, I pulled the plug and no oil ran out, so on my engine at least I can say I get pretty much all that coul dbe drained out from the plug, now my plug is on the side, not on the bottom too, so there wil be a little left because of that.

It's faster but the dipstick tube does not go to the bottom of the oil pan. This leaves some oil that doesn't get removed.

Never wanted a vacuum suck pump because it seemed like a bulky way to make a big oily mess trying to store it between uses. After messing around with drill pumps and things that just didn't suck the oil out...tried one and fell in like with it.

IF you make sure to restrain the suction hose with both hands, so it can't fling dirty oil around the boat. And IF you use paper towels and a waiting bag to clean it up. And IF you double-bag it, with more paper towels in two plastic bags...all the mess can be constrained and you can actually chain the oil painlessly. Without electrical power. Without any splatter or mess.

Whatever is left in the pan, there's nothing to do so don't worry about it. A little old oil won't really contaminate the new oil very much after all.

If you do install a built-in hard-wired and hard-plumbed electric pump, do not place the switch near the companionway.

Depends on engine. On many Yanmars the dipstick tube is externally bolted to outside of oil pain on the bottom. Can't get much lower.

Also remember, it would be better to change the oil more often because it is easy, even if 10% of oil is left behind, than labor for perfection but change the oil less frequently because it's such a PITA to extract every last drop.

My Westerbeke pan is impossible to reach. It has a piped electric that is magnificent. I highly recommend this if you can pipe to the oil pan drain port. Perhaps a Banjo fitting?

To the OP - FYI the west marine oil extractor is on sale for 40% off today (Friday). So now it is about the price it should be.--- $60

I use a vacuum extractor I got from northern tool. Called a topsider. You pump a vacuum in the metal can stick the tube down the dipstick open the value. I can leave it walk away while it does it's job. No oil gets in any pump just goes in tank. Put new oil in engine then dump old oil right back in emptied oil. This works great for changing the oil in the sail drives because it can take 20 min. For all the gear oil to get up and out when cold so being able to leave it alone is huge.

Yep, I've pretty much had them all over the years and currently use one like that.

That is the one I have and it works well, but it is a big thing though, I'm thinking drill pump one I begine cruising

"I'm thinking drill pump "
In theory they would work great. In practice? I've only tried to work with two and neither one was worth a tinker's dam. Buy it from someplace that offers a good return policy.
