My 2004 Searay Sport 185 has a 4.3L Mercruiser engine. Last year, my temperature would not increase on the gauge. I first tried changing the thermostat which seemed to be the correct fix. I ran it for a few more hours last year before winterizing it. This year, my engine alarm began sounding once I hit 3200rpm. The temperature seemed a little hot (190ish) so I checked the thermostat again. After checking the thermostat in a pot of boiling water, I realized we had the thermostat upside down. Interestingly, the thermostat I replaced last year was also in backwards. Anyways, after correcting the position of the thermostat I found my temperature gauge would not read any temperature. When letting off the throttle, the temp gauge will jump to 175 and then when I accelerate it drops to zero again. This weekend, the gauge would randomly jump to 175/180 and then drop down to zero. The hoses/engine did not feel overly hot. When turning the key off and tapping the gauge, the needle will increase on the gauge to around 130. I also checked the wires of the gauge and although there was no consistency in what I was touching, the gauge would read a temperature randomly. this has led me to believe I may now be dealing with a faulty temp gauge.
any thoughts/suggestions before I order a new gauge? any recommendations on where to order a temp gauge for a 2004 sea ray? I'm in Canada.
Thanks
