Outboard Oil Extraction

[Brian D]

Time to change the oil in my Suzuki DF2.5 Outboard. I have been meaning to do it since I cleaned out the carburetor several months ago. I got motivated and looked for a device that could get the oil out, but either they were too flimsy or too expensive. And that is just for a one-time oil change.

So I got to thinking. Ob boy, here we go again. So what did I come up with? An empty coffee jar, some hose, and a old Intex air pump.

Drilled the large hole first (just a wee bit too big, dang it) and used butyl tape to give it a better seal. Still had too much air seepage when testing so I used the tape on the cap and that made it better. But I still have air seepage.

Next drilled a small hole for the air pump. That went better and I have a very tight fit.

Now the test. Inserted the hose in the oil tank of the outboard. Put the pump on the jar and turned it on. Whoot. Oil came out. Wasn't real fast but fast enough. Had to keep the pump sucking the oil because when I stopped the pump, the oil stopped flowing. Yeah, the jar was below the engine.

So what do you do to get your oil out?

Oil in the jar! Whoot

Small hole for the air pump. The pump runs in vacuum mode by the way (I knew you knew that).

I use the same oil extractor for diesel engine on my df2.5

A good manual oil extractor will set you back $63 USD. That electric air pump could get you blowed up.

Possibly from the oil vapors? I did not notice anything unusual when it was operating? What would cause an explosion?

Carbureted engine waste oil accumulates gasoline. That fan motor doesn't look like a spark-protected device.

This looks like a nice solution but has a small cost. No electricity required and has a variety of uses. https://www.tractorsupply.com/tsc/p...city-oil-extractor-8-qt-capacity?cm_vc=-10005

This is probably all you need and you can get it with spare change.

Interesting Gunni. I did detect a hint of gasoline odor in the extracted oil. I thought it was my imagination. I'll have to pay attention to that. Thanks for the heads up.
