The first thing to do is disconnect the pipe where it comes through the casing and see if it works then. They normally have a bit of sh*t stuck just on the plastic part that comes through the shell, failing that blow or put an airline up the pipe to blast the sh*t away.

We carry a bit of brazing rod so we can poke the c**p out of the tell tale if it gets bunged up with salt (or sand if someone has a whoopsey and runs over a bank! )

1) Does water come out of the exhaust and how hot is what comes out?

2)What state is the rest of the waterpump-baseplate, gaskets and cover?

3) Are you sure it's not overheating (does your temp gauge/overheat alarm work ok?)

4) Is it 4 or 2 stroke?

5)Has it been flushed after use properly?

hi thanks for reply its a 4 stroke ,it has a brand new lever on it so the alarm should be working,,no water comes out the exhaust at all just steam but some time water trickles out the back and its rather warm to the touch,and it was took and doon by a boat shop every time it was took out of the water to flush it so im told,,,also gaskets and plates seem ok and i added a fine line of sealent as well to see if it helped with no joy

Do you hear the alarm for a couple of seconds when you turn the key on?

How long have you had it running on muffs? Long enough for the thermostat to open? Are we talking about the exhaust point on the back of the leg or what comes out of the prop centre on muffs?

Your alarm isn't working then. You may be overheating. Have you been running it all year without a freshwater flush?

no havnt been running it all year like that just the last few months was told it was ok to fun with no water jut out back and steam from exhaust so came on here to be safe by asking,,also its a brand new lever on it can the alarm fail on that and is there any way to test it???

[Nos4r2]

I should have asked before-What controls have you got? Something like these?



The original mercury commander controls have an alarm built in which self-tests when you turn the key on.

i think it is a merecy control but if you give me 10 mins i will go have a look and then you will know for sure

If it's a mercury sidemount it should have the alarm. If nothing else you need to get the alarm fixed or you won't be able to tell if there's a problem.

it COULD be perfectly ok-as long as your pee stream is working-but with neither working you need to address it.

i have just checked and its a mercury sidemount its a nice fancy one with the name in the middle of the lever and black in colour do you need a picture to see what 1 it is???

My merc four stroke 90 does not self test when switched on, and never has since new despite. My 50 four stroke merc does but not the 90.
Doesnt mean the alarm doesnt work however cos when the original engine blew its oil seal in the oil pump after three weeks it made a helluva noise-followed by a siezed engine and a lotta oil everywhere. A fault not unknown to merc and mariner dealers and I have met others to who the same thing has happened. Mine replaced by sowester and then again by Barrus but thats a long story!

Short the overheat sensor direct to the block and it'll trip the alarm.
