1979 Mercruiser 350ci/260hp Water Temp Beeper?

[stnick]

I'd like to install a audible alarm on my boat that would warn me with a tone or beep when the water temp hits 200 degrees or so. Has anyone got any answers?<br />Thanks,<br />Nick Nichols

Yep,<br />"ISSPRO" manufacture temp alarm switches <br />P/no R363E 200F 3/8" npt for single wire hook-up to a lamp or relay.<br />Check with a shop near you that services Heavy Trucks for supply.<br /><br />Peter

2nd thoughts,<br />If you are RAW water cooled the 200f is ok but if you have a heatexchanger and freshwater cooled then you should use a 220f switch instead.<br />Also make sure that the switch is installed at a point that wont be out of water too soon in the event of a loss of water.<br />Peter
