Where is the crankcase drain plug on a 2016 Mercury 25 4 stroke? Is it the little black plastic "plug" on the right side of the motor a bit below the cowling? If that is it, how do you remove it without buggering it up? There is a hose inside the cowling that runs to it from the block(?).

I have a 2010 30 hp, the drain plug is on the right side below the cowling. I use a six point socket that fits.
Mine is not black it's silver.

It doesn't look like a bolt or nut and appears to be rounded with no flats for a wrench. I'm gonna go ask a dealer.

It sounds like you're looking at the telltale fitting.
The drain plug is a bolt about halfway down the starboard side, as mentioned.
Tilt the motor all the way up and turn it so the bolt faces down.
Now it will drain straight into a pan without running down the housing.

If you google-image it, you'll see pics of a fitting (with flats) with a hose.
Those are the dripless fittings on the new, bigger four strokes - ignore those.

EDIT: If I think of it, I'll try and grab you a pic of one in the showroom today.

Did you get a owners manual with it? Should show you in it.

I found it - thanks.. The owners manual has a lame drawing and just says "remove drain plug" and shows it in the wrong place. Does not tell you to use a wrench or what size the bolt head is.

While we are on the subject of Mercs, does anyone know if there is a mercury compatible remote motor control ( throttle and F/N/R) that would mount on the starboard side (right side looking forward) of a center console? The ones I have seen look like they are made to mount on the starboard side of the boat itself by the gunwale. I'm thinking of installing a bigger motor (40 hp with power tilt and electric start) with a center console and remote controls/steering. I could flush mount the controls, but I am looking at a Todd console and it is not very wide.

The older remotes with the rectangular base have a reversible handle just for that application.
The new ones with the oval base are not reversible and Mercury doesn't have a new product for mounting to the right side of a center console.
Conversely, you could use the binnacle mount control and fab up a bracket or pod that bolts to the side of the console.

Thanks - I'll figure something out when the time comes. Maybe Mercury will come through with a product by then.
