Do you know of anybody else that has done this - I suspect that the oil pan
may have a thicker spot / dummy plug for just this operation?

Yanmars don't have them. In our installation, we couldn't get a pan
underneath to use it, anyway. We were warned off of putting a plug or
drain tube in the pan: possible leak point. I'd rather spend a few
minutes pumping from the top than have the oil drip out of a makeshift
drain while I wasn't looking.

We have a little bronze hand pump with a tube that fits in the dipstick
hole and a plastic tube into the waste container. Came with the boat so
I don't know the manufacturer. Does the job for us in about 10 minutes
and fits into next to no space.

3 possible methods - it any case the oil needs to be at operating
temps to make it easier/faster to get thru a tube

- vacuum sucker like the ones someone else suggested - are relatively
hard to clean and store - I used one for years before the pump quit.

- a pump built for the engine - available as an option for some
Perkins, etc - convenient - stays on engine, no cleanup, would take
many hand strokes for my 8 qts

- a 12 volt pump either vane or rubber impeller or some positive
displacement - I use an old Groco vane pump that I had left over from
another project. Works great. They aren't cheap. 2 big battery clips
and 6 ft of wire. Make sure it's oil compatible. Diesel fuel pumps
would be OK as another said - don't know about lifetime.

Get some cheap 1/4" poly tubing from Home Depot - whatever length you
need and 1 ft of the 3/8" size - it's ID fits perfectly over the 1/4"
OD - so when you're finished - coil the tubing and seal the oil
remains in the tube by sticking both ends of the 1/4 into the 2 ends
of the 3/8 - eliminates drips and oozes.

Best part about the Groco is that it's reversible - recently changed
the 90 wt gear lube in my windwass - sucked out the old and pumped new
stuff back in without spilling a drop.

Hi,

What's the best thing for the money for removing oil
from a motor in the bilge? I bought a drill pump, and
it worked okay. Once! After that it would never work
again. Someone told me about using a basting squeeze
bulb, and that worked great getting some lube out of
a transfer case, but it took quite a while and a lot of
times filling and emptying it. It would take forever to
empty a motor of oil, unless there's a quart size or
something.

Thanks for any suggestions,
David

Jabsco makes a pump mounted on a plastic bucket that works great. I had to
change it to a 5 gallon bucket because my diesel holds 14 qts., but that was
no problem. It works much better than anything else I've seen or tried. As
others mentioned, you can build your own as well, just make sure the pump is
rated for oil and/or petroleum products. If you're in a gasoline
environment, be sure it's explosion proof.

For the last 20 years I have used a suction gun for this sort of problem.

They come in a variety of sizes and are good for getting in tight spaces.

Note the liter capacity unit.

Topsider pump works well but the oil must be hot to flow.
My drain pan plugs have never been out of the engines.
