- In todays video ima show you how to do an oil change on a mercury 115 4 stroke outboard. It’s very simple and easy and can save you money doing it yourself rather taking it to a dealer. Thanks for tuning in!!
Great video bro.. i love those Mercs
straight and to the point!!!! Thank you
Absolutely thank you for the comment/feedback much appreciated
The yellow plug under the oil filter is for attaching a drain tube to. That is where the oil gos when removing the filter
I kinda figured that but didn’t have any hose hose in the shop to demonstrate that. We’ve just always done it like this at our shop cus it creates the least amount of mess. Appreciate the comment tho so peeps can know if they don’t have a sucker like I did
The drain plug where you can attach a hose can that be bought? I just have a nut and it makes a mess.
They come on the engine like that from factory. My guess is either someone changed yours out or it’s an older model? But I would think you could buy this style drain plug for it I’ll see if I can find a part # for you. But then yea it’s way easier u just put a hose on it and it drains super easy
I have the same engine, what size prop do you use?
@@jdiez6830 not sure what was on this guys. This was a customers boat that was brought to the marina I work at not my personal boat
Do you have a separate video for pumping the oil in through the bottom? I was told it needed to be pumped in? Not sure if that’s true
I’m assuming your talking about changing the lower gear lube oil and not this engine oil. But when you do gearlube change you fill from the bottom screw in the gearcase till it come out the top vent hole
Does boat need to be out of water to change oil?
Not necessarily. Def way easier and more enviornmently safe doing it on land. But u certainly could do it in the water as long as your high enough to get to the side drain for the oil
Question. My 2021 mercury outboard motor is blowing white ish smoke when I accelerate. The motor only has 20 hours on it. Boat is always in garage, and intake it out 5-10 times a year. Any idea why it would be blowing whitish smoke? Anything helps
Was it winterized? And this is your first start up? Maybe fogging oil/fuel treatment if so. Otherwise could just be steam
@outboardfinatic Sat in the garage, the last time I ran the boat on the water was two months ago. I added fuel stabilizer before I ran the boat on the water this morning. The only thing I did differently was I pumped 76 gas instead of Chevron.
Hey, I’ve got that same engine, it’s a 2020. I’m have a terrible problem with the spark plugs fouling, I’m currently on my 3rd set maybe 4th set of spark plugs. Is this normal for the Mercury 115hp engine? Do you have any suggestions???
Haven’t ran in that issue myself with any of the servicing I do for customers here. What kind of gas u running and u adding stabilizer? Or over stabilizing your fuel or something. Or maybe running the run spark plugs at the wrong gaps? Just some things to think about
What size wrench for the oil drain plug?
5/8"....
5/8 socket or wrench
Wrench. 5/8
good man good man
Why is he hiding his face
Just to cover my identity that’s all
You forgot the Fuel filter got to be changed 😮. Every 100 hours or one year
This was just strictly an oil change video I did during winterization season. I’m well aware of the routine maintenances and this customer gets those services yearly with us
