Adding a temp gauge to my dash for 2000 90 HP Merc.
All
How hard would it be to add a H2O temp gauge to the dash for my boat 99 Crestliner Fishhawk 1750 SC with a 2000 90HP Merc. Also anyone have any suggestions as to where to look to find why the tilt trim gauge doesn't work. Fredo |

Fredo Fredo, an aftermarket temp guage will come with a "paste on" temp sensor that is secured to a specific location on the motor's head. You may have to scrape some paint away at the location of the installation. You route the lead from the sensor is routed to the dash panel, and connect to the gauge. The guage should have a positive (blade) and negative (stud/nut) for power, and probably an extra terminal blade for the lighting control circuit (from the nav/anchor switch or an adjacent gauge). I believe some of the newer motors with electronics built in have a temp sensor as part of the mechanicals, but I don't think that describes your 90 Merc. I installed a trim guage on an OMC powered boat last year, and if...a big if...I recall correctly, the gauge readout is based on varying resistance (ohms) through the lead wires. You can take a volt-ohmeter and measure the resistance with the motor in different positions across the gauge terminals. If the resistance reading doesn't vary, it's something at the motor, probably the sender, or faulty lead wiring. If you get variable readings, then the gauge is stuck/malfunctioning. |

Is your motor 2 stroke or 4 stroke? 2 strokes usually just put a sensor on the head, 4 strokes have a place for the sensor in the water jacket up near the thermostat housing. Teleflex has details on their site. I have also become a believer in water pressure guages. They warn you something is going south before you start overheating. |
