Hi All,

I have been trying to get my temp gauge working on my 99 montauk/2000 90hp 2cyl saltwater merc and am having some problems that maybe some others can help with.
First thing I noticed is the sender was missing. Wonderful since the dealer I got it from is no longer in business and the boat is out of warrenty, soI ordered the part number whaler gave me for the kit 12415a2 and installed it. I still noticed my gauge does not seem to move. So I took a hair dryer and heated up the the sender, the gauge did move but just barely off of the 'C' mark. I am guessing the gauge should move alot more than that?
Anyone have any ideas how to troubleshoot this thing? And does anyone have any idea
how hot temp wise this engine usually runs
at say 1000,2000 and 3000 rpm.

That guage will not move until it gets oover 100 degrees. hairdryers do not get very hot so.....

Most outbopards run under 150 degrees and the guage should be on the low side when running.

Hi JohnP,

I bought a brand new 2001 Montauk with the factory installed Merc 90 2 stroke. My hot/cold guage still does not work.

When I turn on the ignition it does move ever so slightly.

I found a sender wraped in a plastic bag under the center console. I believe it was directly below the throttle (or maybe it was directly below the ignition key).

I had to bring my boat back to the dealer for the Overcurrent Protection Warranty and I asked them to take care of the sender. I assume they swapped them. Nothing changed.

There is a thread approximately a year ago where it was suggested to install a lower temp sender. The part number was given also.

I am quite sure you meant to say 2 stroke 3 cylynder engine. We have the same great engine.

Spellcheck: cylinder

GAwhale 3 cylinders is right and it is a super engine.
I guess the only way to really test it is to pull it out and put it in some hot water that should give me some idea.
It should'nt be such a big issue because there is an overtemp alarm but I am retentive and I insist if something is in the boat it better work right.
