Oil Changes

Tim R. · Nov 4, 2009

Pull the pan and add a drain coupling that can be connected to a hose with plug on the end. This way you can use an electrical pump to pull the oil out of the hose. A lot of Universals are setup this way and it works great.

I warm up my engine and shut it down. Connect the electric pump to the hose and it pulls all the oil out in a couple of minutes right into a 5 gal bucket.

I use an Oilboy. It won't get the last drop, but is not messy. You can punch a small hole in the filter to drain that before removing it. http://www.amazon.com/Tempo-Oil-Boy-Fluid-Extractor/dp/B0000BYP0L

Through the dipstick tube, using either a hand pump or electric pump. Many are available at WM, Defender, etc.

Haven't done a clean/neat one in the 19 years I've dealt with the 3 GMF I am seriously considering the drain plug installation this winter.. I usually use a little electric drill powered vane pump .. even that is a two person job to keep all the black gook more or less contained.. When I get around to it, I'll take pictures of my modification and post 'em ..

Has anyone come up with a really neat way to change the oil on a Yanmar, without a drain plug. I have tried about everything I can think of, and still have the same problems. Takes forever to get it out, and always makes a big mess. I spread plastic trash bags and paper towels and diapers on the floor, but is still a real PITA. As I believe I can get the pan off mine, I am very tempted to pull the pan, and install a drain plug in that puppy. Then will just have to figure out what to stick under there to drain into. Any suggestions appreciated.

this is what I did years ago. pulling it out of the dipstick was a joke. Put a tube on it and hook it up to a pump as other suggest or just drain into another temp pan - it's only like a couple quarts.

Suck it out.

Yes, you leave a few drops, but it is dead easy. I like the units that vacuum into a tank better than the pump units. Very clean. The pump units can get messy if something comes loose.

I was at a show the past week where a vendor was starting to market a similar system to pump the oil out of cars. It seems a few brands are removing the drain plugs! It saves a part, a leak point, and gets the car back into the dealer for service.

After 35 years of oil changes I am sold on the Moeller Fluid Extractor. I has changed my life. West has them. Nothing to it. Insert tube down dipstick, pump canister a few times, walk away. Come back in 5 minutes or so and the job is done.

I recommend the vacuum units. Have used the Pela 2000 for years on my 2 cyl Yanmar. Never spill a drop of oil and very easy to use.

I am with Higgs (Moeller Fluid Extractor). It gets most of the oil out with a single cycle. If you want to really clean it out, you can empty what you can and then add fresh oil and pump again. I think that is an overkill.

If you have a GM engine the oil get fairly dirty after just a few hours anyway.

The Moeller units have a better quality plastic tube that does not collapse when it starts sucking the warm oil.

PS: The Pela 650 looks exactly like the Moeller unit. This was also a Tempo unit too.

I got such a similar unit for $10 at Harbor Freight Tools. It's a gallon or so can with a screw on hand pump on one side, and a screw on nipple on the other. As other suggest, had to add $1 worth of copper tube to fit down into the dipstick hole. Attach the plastic tube to the copper and put it down tot he bottom of the pan. Clamp the hose shut, pump the handle until all the air is removed from the can, release the clamp, and it should extract most all of the oil in the pan. Not much really comes out of the filter, but the idea of punching a small hole is a good one. Take the can to the recycler when you're ready and pour out the old oil. The job is done.
BTW, what are some oil filter brands/numbers folks have been using on the Yanmar 2GM-20?

Steve Dion · Nov 4, 2009

Yanmar Filter. Overall your best bet. If you read the horror stories about some of the brand x filters you may agree. How much money do you think you can save by purchase brand X once a year? Some of the owners pay more for brand x vs. Yanmar.

I think you can get the Yanmar filters at your local tractor supply too.

Steve, for the 2GM, is that currently the 35100 or 35150

I agree too. I have been using the Moeller unit and it is amazingly simple, clean and fast. Make sure you run you engine for a while to get it up to temperature. The oil flows better.

Oil change

I've been using the Topsider oil change system ever since we purchased Belle-Vie in 2002. Our boat came equipped with a four cylinder Yanmar and a Cummins three cylinder diesel genset and the Topsider makes changing the oil easier than changing the oil on our car.

The two gallon metal container comes with a vacuum pump that when created will extract the oil from the engine via the dip stick tube. While it does its work I can do other chores. It usually takes about ten minutes to empty the four quarts from the main engine and it gets just about every drop out. No mess no fuss.

Yanmar changes the part numbers from time to time. Your Yanmar dealer knows what part is current.

Scott B · Nov 5, 2009

Torresen also has a good parts listing for all the Yanmar engines and is kept current.

Yanmar Torresen

If you follow the 2GM Oil Filter you eventually find the current part # 35151-12

I made my oil pump from a chemical dispenser pump that goes in a gallon jug. I took a 3' piece of plastic waterline for an ice maker on a refrigerator and put it in the bottom of the pump. I used a small hose clamp to hold it in place. I then put a 3' piece of soft plastic tubing on the top end of the pump and held it on with a hose clamp. Then I inserted the hard tube into the dipstick hole, and the soft tube into a gallon jug and started pumping. the whole thing costs about $5.
I have a Yanmar 2 gm and it emptied everything in a couple of minutes. I let the tubes drain good for about 5 minutes and pulled the tubes out and wiped them with a rag. Job done. I wiped up about three drops of oil when I was done. If you have an motor with a lot of oil in it, it might be easier to get an electric or vacuum pump. Any restaurant or commercial kitchen will have the pump. Thy get them for free with their chemicals. Most pumps pump about 1-2 oz per stroke. It's probably not the best pump in the world, but it works.
I think that the biggest thing about changing the oil in any boat is to take your time. Don't rush. When you get in a hurry, things get spilled, no matter what kind of pump you use.

once the old oil is removed, install a hose out of the bottom of the sump and attach a brass fitting that matches up to your pump's fitting if available and suck the oil right out of the pan....no more dip stick....and no mess and really clean oil in your engine....no more black for awhile...Pat

another vote for a vac extractor

I tried using one of the old Jabsco style piston pumps that came with the boat...didn't work at all. Bought a Pella oil extractor and it was worth every penny. The neat thing about the Pella is that the movement of the piston doesn't pump the oil. The pump creates a strong vacuum in the collection vessel and that pulls out the oil. So you set it up, pump the chamber down and walk away. It's done when its done and you can do other things. I was actually surprised that it very little time to pull all the oil out. It came with a narrow diameter but stiff pick up tube that won't collapse under vacuum and which is easy to fit into the dipstick port. This was important for me as the dipstick on the 2QM15 is on the wrong side and tough to get at on my boat.

As a bonus, the Pella 2000 is small enough that it is easy to haul around. It is smaller than a basketball packed up so I take it to the boat but also use it around the house on all my power equipment.
