Don’t keep oil in the container. It degrades the seal. I had to replace one on my mityvac. Shipyard Island Marine (SIM Yamaha) sold an oil fill fitting that screwed onto my F250s’ filler tube for the vac.

 

Is there a reason to do this instead of just draining the oil out of the engine and lower unit when you do your service? I'm new to outboards. But my service intervals for lower unit oil and engine oil are 100 hours. I have to trailer the boat to do the lower unit gear oil. Why not just drain the engine oil at the same time?

 

Yes on the new Yamahas they buried the plug under the motor covers and so you would have to remove the covers to drain from the plug. This involves many screws.. A total pain. I did it once and will never do it again. However the oil exactor does work ok except it is slow..

 

The reason I want an oil extraction pump is less mess. I have twin Yamaha 200s and there isn’t much room between the motors to get a drain pan. Once you remove the plug the oil comes screaming out, at least it did for me, which in turn made a mess.

 

3/8ths vinyl hose. Stick it in the dipstick hole, suck on it and let it flow.

 

That's terrible, glad I did not go that way. My whole career as an engineer has been to make things easier to fix, not cheaper to build. Those guys that designed that system have never touched a tool or tried to repair anything. My suzuki has a plug bolt and a drip proof port the oil just pours out of. Set a bucket on the ground and unscrew the plug bolt. The oil filter sits in a recess and the oil drains back into the crank when you unscrew the filter. No spill, easiest thing I have ever worked on.

 

Terrible? Hardly. I can easily drain my oil pulling the plug on my Yamaha, but I choose to pump it out because as far as I'm concerned it's easier, with nearly zero chance of making a mess. Stick the hose down the dipstick tube, give it a couple of pumps, and watch the container fill while you drink a beer. When it's full, dump the used oil into the receptacle of your choice. There's no need to dirty up an oil pan or bucket, nor let the wind blow your draining oil all over the lower unit or driveway. I'm also not limited as to where I can change it. A simple West Marine oil pump has served me well for a couple decades.

 

That works too. At least on my F200s. Peel off the right side of the center cowling and unscrew the plug. Takes longer.

 

On the Suzuki DF300B you just unscrew the bolt. No covers involved. Those guys would not drop a wrench if you tossed them one.

 

Clearly a better design but Joko was asking about a Yammi 200.

 

Mightyvac works great, haven’t needed it for engine oil changes but have changed my trim and tilt fluid with it and bled brakes with it. You would probably need the larger one for an engine sump

also use mine For checking crank case leaks on my chainsaws and checking leak down on your lower unit on your outboards. Also can Pressurize and pull vacuum to chase leaks in your fuel system. Mine came with a case with about two dozen different adapter rubber fittings and different lengths of clear vinyl tube

 

Go with an electrical one. Use it for all of your vehicles. Turn in on and do other stuff for a few minutes easy and no mess.
When moored I did engine at 100 hours and lower unit oil annually.

 

I agree that it is cleaner for a guy like me. I have a tendency to make a mess of this process. Yamaha is saving me from myself. At first I did not like it but now I do. I just need to choose the right replacement extraction devise. As far as siphoning the oil, that is a no go. The oil is to thick to drain that way. It would take Avery long time. Even with an extractor it takes 15 min to get the oil out and that is with a fair bit of vacuum pressure

Actually I've done this with 3/8ths clear vinyl tubing and drained out 5 qts in about 5 minutes. Once you get a flow over the top bend gravity takes hold and continues flowing as long as the hose end in the crankcase has oil to suck up. Maybe I'm just very lucky or special? I tend to think if it works me me it can work for anyone.

 

I use a cheap hand pump from Harbor Freight. Works great and less than $20.00.

 

I read once where a person pulled the nylon/ plastic extractor tube out sliced part of the tube and was left in crankcase. Does this sound possible?

 

I use one like this. Very easy and I can change engine oil on the dock if needed but easier for Yamahas with the stupid hidden drain plugs. Has worked well for several years. Lower units are just a on e a year drain in the shop and refill.

 

I have this one, works great.

Thank you all for the helpful suggestions. I appreciate it.

 

I changed oil for years on my twin Yamaha 225’s with a unit very similar. Worked just fine, sometimes a little slow.

Regarding the drain bolt….. I usually changed oil in the slip while moored. Since I was high usage, I extended the gear oil out to mid season or annual depending on usage. 4000 plus hours on twins (so 8000 plus hours) and never a lower unit issue. I’m comfortable with the 200 hours or annual on gears if used frequently. No way I was going to pull an oil drain bolt. When on land…I still used this as it was cleaner and I never worried about a leaking oil drain bolt. If I DID want to pull the plug, it only took a couple minutes. Not a big deal. Definitely not an engineering issue unless you want to overthink it and call it one.

In hindsight, after using this type for years, I wish I would have ponied up and bought the Jabsco electric oil change kit right off the bat. It is about $175 for the standard or $250 for the reversible on Amazon. No pumping, no waiting, just quick and done wherever you are. It’s a no brainer for me now with diesels as it’s reversible and pumps the fresh oil back into the pan. Would have been SOOO much easier and quicker on the water at all my 100 hour changes.

Here's another comment for ya. I have a 12 volt battery Shurflow extractor that I just hook up to the boat battery or a back up battery pack thing from Costco. I comes with a bucket attached and does a quick and easy job. I also have a Yamaha 200 and it's quicker cause you don't have to take the housing off to get to the drain plug. Also, the aluminum drain plug threads can be stripped if you apply just a bit too much torque - yeah you're thinking an idiot would do that but I know of more that one person this happened to and it's a hassle to fix. I have done it both ways and for sure on the Yamaha the extractor is quicker and cleaner - manual, 12 volt battery or electric extractor.

 

 

I use a Sur-Flow 12 volt oil extractor pump that attaches to my 12 volt battery. This works really well and is fast and not messy or a hassle to use. I find it much easy to a manual pump, as effective or more effective at sucking all the oil out of the bottom of the pan. Highly recommend. Lasts forever, I've had mine for greater than 5 years no problems. I also have the Yamaha 200 HP outboard and for sure much better than taking the housing off and dealing with the plug (that can be stripped easily if you're not careful). Tight Lines! JB
