Oil Change Pump Extractor

I have a vacuum hand pump one I have to use on jet skis -- don't remember the brand... picked it up from Amazon.

I do not recommend those as they do not fully extract the oil

Generally the oil drain is easily accessed under the generator. Way better way to do it.

I used one to change mine. And then un did the drain plug anyway to see how much was missed, lol. First time changing the oil in it.
I wouldn’t buy one for that, but after getting one a few years ago primarily for changing my boat engine and v drive oil, it’s pretty handy around the shop.
