Re: water pressure gauge

There is a connector on most Mercs on the water cover usually between the plugs. You can hook it up to that.

Re: water pressure gauge

I am a new boat owner and also thinking of adding a water pressure gauge. I have a Mercury 150 Saltwater with a "water temperature” gauge. The range is 0 to 220 degrees, initially didn’t notice it registering beyond about 175, then I noticed it was up to almost 200. I contacted my local marina and they said “ Mercury’s always run hot”. I didn’t like that answer and contacted Mercury who basically said the same. They did allow that they wished that the boat manufacturer wouldn’t put “temperature” gauges, rather a water pressure gauge which “they” said tells much more. There are too many variables when using a temperature gauge…and sure enough after 10 hours of use the temperature now runs anywhere from 160 to 200.<br /><br />Any comments on this would be appreciated.
