2012 115 hp oil drain plug

[LLAMA310]

Where is the oil drain plug located on a 2012 115 hp yamaha 4 stroke? Or do you have to pump the oil out of the oil fill to remove?

It is right where your owner's manual says that it is

some prefer to suck it out to keep from cross-threading and/or stripping the threads of the drain screw.

One less thing to worry about

Oil drain plug

thanks for the info. My owners manual does not say anything about draining the engine oil and there is no diagram like you sent. It tells how to change the gear oil and a lot of unuseful information. But thanks again, you have answered my question.

That's probably what I'd do also, as understand a stripped out drain screw hole is a real bugger to repair...just use a pump...

Yamahaoutboards.com shows only two owner's manuals for 2006 and later F115's.

I would agree with the others however. In less time than you can remove the drain plug you can suck the oil out of the oil pan. With no risk of cross threading the plug or of stripping the oil pan threads.

Almost time to change my oil, so this of high interest to me.

What kind of pump is suggested? Or do y'all mean just suck the oil out thru a soda-straw?

[boscoe99]

A vacuum extraction device with a storage tank is typically used. Or, they also make electric pump driven extractors. Just depends on how much money you want to spend.

I got a ten dollar flexible vane pump from Home Depot that goes onto the end of my drill motor. It will pump all of the oil out in record time. Just pump it into a bucket.

Yep, just suck it out with a soda straw....but don't swallow too much...kinda rough on the digestive system.....

Why all the paranoid people about changing the oil by removing the sump plug? it is no harder to strip or cross thread it than any other bolt, sump plugs get removed all the time.

If there are two alternate, equally effective methods of doing something, and one has the potential for damaging the motor and one does not, why take the riskier approach? Not to mention that the method with lesser risk is faster and less messy.

I have seen engines with damage from improper installation of a drain plug. I have never heard of an engine being damaged from using a vacuum extraction device.

In the end each is free to choose. Some choose not to change the oil at all.

If you can't screw in a drain plug without cross threading it, you shouldn't be wrenching on it, period...

[rodbolt17]

it happens.
occasionally the AL threads gall to the steel plug and strip on removal.
some get overtightened and strip.
some get cross threaded.

it happens enough that I have some specially modified heli-coils, a modified drill bit and a modified heli-coil tap just for that.

for 100 bucks I can rethread (heli-coil) that bogus thread.

Thousands of professional mechanics throughout the world would have to quit their jobs if what you say is correct.
