Well as warmer weather will be approaching us before too long - its time for my 115's first service soon. I'll be doing it myself.
It's a 2012 Merc 115 4 Stroke - besides changing the oil, oil filter and gear lube - is there anything else I need to do - spark plugs, etc...?

Thanks!

Nope. That's about it if everything's going great with the motor.

You'll be good for another year. Just watch your oil level.

In almost if not all cases you'll also need a grease gun loaded with some good water resistant grease. If you look closely you'll probably observe three or four Zerk fitting that will require a couple of shots each.

I would toss on a new fuel filter, too. Just to be safe. They are cheap enough!

I forgot to mention your prop. You will want to remove it and clean out any foreign material and old grease and then liberally apply new grease to the splines and reinstall it again. We don't want our prop galled to the splines should we ever need it off to change it especially out on the water.

Spark Plugs should be fine. No hurt to pull 'em and clean' em tho
