Oil change-drill pump problem YSM12

That is awsome. It looks like it pulls air out of the container instead of pumping oil into it.
I need to install a hose to the oil drain. I wish I would have done that when the engine was out.
Is the connector proprietary to the pump or is that something you added?

Another Oil Change Tip

While on the subject, I found that a dog pee pad (like an adult diaper pad) works better than anything else to catch any oil lost from the filter during an oil chage. Much better than paper towels, rags, bilge pads, etc.

extractor is worth all the money! After your all done you seal it up, take it to the parts store and turn it in! They drain it and give it back to you ready to go for the next time! No mess, no fuss, and it's no time to get it done. More sailing, less swearing.

Hermit, the video is very impressive and that is probably what I would do if I had a large motor, but little the YSM12 motor has a capacity of only 3 liters and does not have an oil drain port or a removable oil pan. You have little choice but to suck the oil out using either the oil filler port or the dipstick tube. I found it best warm up the oil by fast idling in gear for about 10 minutes (while tied to the dock), then insert the stiff slender suction hose that comes with the pump into the dip stick tube and put the pump discharge hose into an empty plastic bottle. As previously mentioned, the YSM12 oil capacity is only 3 liters and I have never been able to get all of it out. When not in use, the hand pump with hoses attached resides in a dedicated small ice cream bucket wedged between the stringers under the motor. There is no cleanup other than a couple of pieces of paper towel to wipe the suction hose. The plastic bottle is emptied into the marina oil-recycling container and the empty bottle goes into the marina plastics-recycling container. You don’t have to transfer the oil into another container for transport or clean the inside of the pump. I don’t understand why you are worrying about it; most people change their oil somewhere between 50 to 100 running hours. That usually means once a year.

No it's real and guess what that engine has 3000 hours on it !!!!!!!!!!!!!!!!!!!!!!!

Yes with a few handle pumps it creates a strong vacuum in the canister...

I need to install a hose to the oil drain. I wish I would have done that when the engine was out.

Yes adding an oil drain plug is a good idea on those older Yanmar's.

Is the connector proprietary to the pump or is that something you added?

Only proprietary by way of the Home Depot brass fittings aisle... A barb, and a coupling...

Actually, if you look on the port side of the motor, all the way at the bottom of that castiron block, there is a drain plug that will drain the main case completely, if you have a few people stand on the port rail for a few minutes. The plug is right above the flat motor mount and drains it all over it and the bilge since there is no way to catch it all under the engine. The first time I changed the oil I used that drain plug to try and get the remainder out after using a crappy pump through the oil fill hole. It was a disaster and all in the bilge.
There is a drain on the gear box at the very bottom also. I need to run a line to that as well to drain the oil out of there.

I'll have to have a closer look. Maybe the plugs are blocked by the hull stingers.

Oil Changers

I have tried them all. And really didn't think any were the cats meow. The Yanmars, and other engines without a drain plug are a little different than those with a drain plug. I changed oil in a Universal once, had a drain plug and a little electric pump. Neatest deal I ever messed with. On my Yanmars I have used the hand pumps, the drill driven pumps and other suggested deals. None of them worked really well on the Yanmar, and most were very messy to deal with. The two drill driven pumps I have had only lasted for three or four oil changes, then died a sudden death. I just purchased a small one gallon shop vac at wally world. Going to give that a try in a couple of days. Costs 25 bucks, and plan on sucking oil directly into it, and using it for nothing else. Will let you know how it works.

I've tried those drill pumps on previous boats, and it didn't go well. My Bene's Perkins has a built-in hand pump, five or six strokes and it's empty, minus the filter.

 

[Hermit Scott]

I like the idea of the built in pump, maybe hook it directly to a through hull so there's no mess.

Oil extractor

I am not sure why try to out design an oil extractor. It doesn't cost that much more than a few of those drill pump. Much less than filling up the landfill.

It does take a few hard strokes to create and maintain the vacumm but not too bad. When the oil is hot, it sucks out easily. Last year I use a vacuum cleaner to create the vacuum. It works well. Any time oil come in contact with rubber, rubber will swell. The oil extractor separates the oil from the suction mechanism.

Becareful with using the vaccum cleaner directly. The oil mist will quickly clog up and swell the foam filter and you'll have another item going to the landfill.

Hey Maine Sail, how much oil is in that engine of yours? My M25 uses almost exactly a gallon (maybe a half quart less). How do I know? I always pump it back into the 1 gallon jug I buy it in. From your video it looks like you have a lot more oil than I pull out of my M25.
Now on my 7.3L International diesel in my F250 I used 15 quarts of oil (thats a lot of oil). Oil changes would cost me around a hundred bucks.
