Mercury Pee Hole ?
 

1988 Mercury Black Max 175
Water seems to be circulating fine.

I have never owned a mercury before.

At idle should the water that shoots out the pee hole be a little warmer then others outboards say (evirude and yamaha)

I read on iboats that the pee hole water in the mercurys doesn't shoot out until the thermostats open up.

All the others motors I have owned except my 225hp seadrive the water came out almost as quick as the engine started.

thanks

I posted on other thread, but yes, water will be hot because they don't pee until up to operating temp, 135 or so I believe.

Yepper, Airslot is correct on that. ;)

Mercs are usually equipped with 158 degree thermostats.

deshet..if you dont have one yet..i'd highly recommend a laser thermometer ,they like $30 at harbor frieght....that way you can get some acurate temps on each cyl and head.

Stink, your buddy may have removed the thermostats.

My buddy cant even change a spark plug so I highly doubt it lol. ::)


I have heard it cause that though. Maybe the previous owner did. :)
