Hello!
Well I purchased a major project: 1982 27' SeaRay Sundancer w. twin Mercruiser 5.7s. Gonna take a lot of work to get these overhauled but I'm well on my way and everything is going great so far.
One thing I'm going to insist on is installing audible oil pressure and temperature alarms. I see that Cole Hersee makes exactly what I'm looking for, but I have some questions I was hoping someone can help me with:
Thanks in Advance -

One thing I'm going to insist on is installing audible oil pressure and temperature alarms. I see that Cole Hersee makes exactly what I'm looking for, but I have some questions I was hoping someone can help me with:
- I imagine this is the way it operates: The body of each switch is grounded to the engine, when a certain value is reached (too hot or not enough pressure) the circuit is completed and the buzzer sounds? So the buzzer is fed a “hot” wire and grounds out when one of the switches gets tripped? Is this correct?
- Are there already made locations on a Mercruiser 5.7 where the switches can be screwed in to? If so, do you know where they are? Are the threads universal or do I have to buy the Cole Hersee Chevy version?
- Are there any other brands that make something similar? If so, which one would you prefer and why?
Thanks in Advance -
JC
