Kind of pricey but I've used this one before with great results.

I've used this one also and found the connections were lacking as it popped off a lot (making a mess). I had to add hose clamps to get enough suction...plus I needed to stop half way through and empty it as it would fill up before all the oil was out.

I've been using one of these for 13 years and it works great. Juyst make sure the oil is warm and it will pump the oil out in a couple of minutes.

I second the MityVac.... that thing works great! No matter what way you go, the warmer the oil, the easier the extraction.

Default Oil Extractor

Try West Marine. They have a 6.9qt unit for $80. I've been using one for a number of yrs with no problems. Wish I'd gotten the smaller one. My engine only holds two qts.

This is the unit I have used since 1998

Most any of the above will work well. Though they seem pricey they're about the cost of one oil change at the marina!

Default Hmmmm

Do any of these give you the confidence that you are getting all of the sludge and contamination out of your crankcase?

There is something about having the plug out and watching the oil drain to the bottom of the pan that seems right. But, I'm willing to learn from someone else's experience.

Depending on the type of engine you have it's pulling from the same level.

For instance, if you have a Merc 496 the dipstick line is on the opposite side of the plug.

You don't put the hose down the dipstick tube. You use the tube to pressurize the engine and the pump sucks it out through the tube.

Good question on sludge. Pulling thru the dipstick is the only option I have. My boat is a 1997 with 1200 hours on the engine. I don't let my oil get to dirty and have always changed it at 70 hours or less so I hope not much sludge is ever there. Runs great and doesn't burn any.

Lightbulb From "Extraction", Expect Sludge...Try a "Rinse"...

After extraction of the old oil, adding exactly one quart of new ATF (or high-detergent oil), then measuring what gets extracted should answer that question.

Check clarity of the "rinse" for sludge and contamination. The ATF "rinse" can be re-used to lubricate chainsaw bars or—like WD-40—to attack corroded hardware.

The extractor that I have uses a small diameter nylon tube that I place down inside of the dip-stick tube. This allows me to go to the bottom of the oil pan and suck out all the oil, without leaving any on the bottom.

Will it get every drop? Who knows, but you're splitting hairs here.

This is the unit that I have:
http://www.amazon.com/America-5060-T.../dp/B001445IZ8

I also use it on my cars. It's so easy and you don't get a drop of oil on yourself if you are careful.

Default Draining oil from a boat engine

I've been using this technique for decades!

http://blog.boattrader.com/2013/08/o...rain-hose.html

It's a lot cheaper and less mess than other methods.
