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.
 
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.
 
Here's some Johnsons for our friends:

For most of us it's these two:

Are the thermostats on these failsafe?

Can the get stuck closed? Do they open and close like it a car or do they just stay ope was you reach operating temp?

thanks
 
He be correct! Mine is hot as piss...my buddys Johnson is always cool.

That didnt sound right.

It sounded just like you!! Your piss is hot and your buddy has a cold Johnson!!
Show him your thong pic on the bracket, maybe his Johnson get warmer!!

HAHAHAHAHAHA!!!LMFAO!!!!!!!!
 
dropped lower unit yesterday and insttalled new water pump.


I reinstalled the lower unit and it pees water fine, but I don't have any forward or reverse gear. i do have some forward gear if I go all the way forward. Do I have to drop the lower unit again?

It there a easy way to line every thing up? I tired to line up the gear shift in the lower unit but I could not see how to do this.


thanks
 
Yes, your gonna have to drop the lower again. After you drop it, put the shifter in forward....then on the lower unit rotate the shift shaft, can't remember which way. I want to say that the prop should rotate freely in reverse when its in forward, but it won't rotate in FWD at all. Then reasseble everything. Make sure that the water tube and shift shaft line up while putting all back together.

Good luck
 
Got it running it is peeing and shifting well.

I am going to install the thermostats but do I really need them?

Should water come out the exhuast ports in the mid section directly below the block?

thanks
 
Yes, you need the T-stats, she'll burn cleaner running at the proper temp. Yes, water will come out the exhaust ports in the mid section, I want to say even before it warms up, but its not alot of water on the muffs, probably because there is no backpressure?
