Oil Extraction System
 

Looking to buy an engine oil extraction system. Looking for any recommendations that would screw onto my threaded oil filler dip stick opening..
Thanks

What ever you get, make sure the discharge tube has a good secure connection to the pump and fitting. Why do I mention this? Mine has a rubber deal and a hose that slips over it. Well, after a while I guess it lost it's grip and as I was happily pumping out dirty oil the hose blew off and sprayed oil all over my cockpit until I could shut the pump off. Not a good deal.

The best thing you can do for your engine and simplicity going forward, is borrow one from a local marina or friend. Use it one time to get as much as the oil out as they get. (They often leave 1/2-1 full quart in the pan.)

Once you evacuate all of the oil, remove the drain plug and allow what's left in the pan to drain out into a few oil absorption mats. Then install an oil pan drain hose kit. Mercury sells them, and a few other parts houses do as well. It's been discussed on here quite a few times.

This is the BEST way to change your oil, (draining it from the bottom of the pan) as it gets ALL of the oil out. This is why Mercury is installing this kit on almost all engines now. It's a lot easier to change your oil with the drain pan hose kit. You just extend it out the bilge drain hole in to a can/bucket/whatever, and walk away. You don't have to drag anything dirty/oily into/out of the boat.

I've used both of these oil change pumps with satisfactory results:

If you take the oil drain plug out what you need to do is take a Prestone empty jug and cut a huge square in the side of the jug. Next place that under your oil pan laying down flat with the cut square opening facing up. Take your oil drain plug out and let the oil drain into the jug , while the jug is filling up, use your oil extractor to suck that oil out of the jug while it is draining. When your oil has completely drained form the pan suck the last drops up with you oil extractor or use the oil pick up sheets, then pull the jug out. No mess at all.

Also it is wise to buy an oil drain hose to replace the oil drain plug. You can use a connector to that oil drain hose from your oil extractor to drain the motor oil out. We do this on all wake board boats as the oil drain hose is not long enough to go thru the water drain plug hole in the transom. Again all oil or most gets drain from the oil pan and no mess.

If you want a pump that really can suck and fuels as well google the Slurper. many marine shops use this as well. I use to have one many years ago.

Also www.liquidynamics.com many shops use this as well.

I think the OP is looking for an oil extractor which screws onto his dipstick tube, rather than one that inserts a smaller tube down the dipstick tube. I have a friend looking for one of these was well. Anybody know where to get one?

This is what you need. Yeah, a bit pricey but they last forever. I've had mine for 25 yrs.

You don't need to screw it onto the dipstick. It's a garden hose fitting BTW.
All you need is a hose that is the same ID as the dipstick tube top is OD. Slip it over and turn the pump on. The dipstick tube goes all the way to the bottom of the pan, but by design it's not going to extract/suck ALL of the oil out.
If you need to change hose diameter, 10 minutes in the plumbing isle at Lowes/Home Depot and you can have a couple barbs and new hose diameter up or down.

I just change my oil every 25 hours. If 1 qt is left over it's no big deal. I just can't get myself to trust a rubber hose hanging off the bottom of my pan. If it tears for whatever reason you can't stop the oil from flowing out.

This is what i use. choose the tubing size you like. 1/4" O.D. goes down threw the dip stick, 3/8" I.D goes over the opening.

I go threw the dip stick tube. Hot or warm oil after a run is way quicker to pump ;)

These are cheap and work great.

Use a short "washing machine" hose to go from the pump to the dipstick. Screws right on.
And, if you can get to the pan drain location, you should put a drain hose kit on it long enough to be handy for you. I've NEVER heard of one failing and losing somebody's oil.
