Thread: Mercury (Tracker 1996) 40 overtemp alarm

I have replaced the waterpump impeller and am getting a good stream of water out the pee hole but keep getting over temp alarm, don't know of a outboard motor machanic around here, any ideas or is there a good web site to go to.

Check the thermostat. It may not be working properly.

Here's a crappie.com member that is a outboard mechanic in Paris,Tn, and he
has worked on my boat motor, and he's a good guy, call him he'll help you out.

Thermostat can certainly cause it. Does the steady beep come on immediately or after running a while?

After about 3 to 5 minutes of running the alarm starts going off. I didn't know it had a thermostat will check that out. This started after a day of fishing on Truman (MO) when it was high and dirty.

If you have trouble finding it go here http://www.mercurypartsexpress.com/P...phome.asp?CID=

and put your serial number in and you can look at exploded views of your motor.

From the drawings I don't think there is a thermostat on this motor.

Could the overtemp alarm sensor be bad??? just a thought.

Here is an excellent web site you can ask at http://forums.iboats.com/
