Water temp gauge

RichardD

My 226 hurricane has a "blanked out" space for an additional gauge. I would like to add a water temperature gauge. My question is, does the wire harness from the motor to the dash contain the required wire from the sending unit on the 115 yamaha? If so, which one wouldn't be?

If it is like the f150 you have to remove a plug from the engine and install the sending unit then run the wire from the sending unit to the gauge.  I installed a water pressure gauge in my empty dash hole, and the water pressure plug is very close to the location of the plug you remove to install the sending unit for the temperature gauge on the f150.

I just looked at the rigging guide for a f115 engine.  There is one port on the engine instead of 2 like the f150.  You can use this port for either a water temperature gauge or a water pressure gauge.  You would have to buy the temperature sensor, which comes with the wire to run to a gauge.

Thanks Ernest T, after thinking about it, I'm going to install the water pressure gauge as you have. It makes more sense than the temp gauge. First off, the engine has over temp protection built into it as I have read. If the pressure drops, the temp is going to go up as the result anyway. Plus, if watching the gauges, you'd catch the problem earlier. Thanks.

I came to the same conclusion on my boat.

I just installed both temp and pressure guages on my yamaha 150. Only problem is fishing the tubes from the engine to the console. But that has always been a problem with the 226
