Should it be a quicksilver guage?
I have an infra red sensor
where would i measure the temperature from?
What temperature should i expect?
I asked if it's a Quicksilver as they were the original units and unlikely to be miles out on the calibration whereas if it's an aftermarket unit it may be the wrong one for the engine and need 'adjusting'.
I'd measure the temp of the water jacket around the spark plugs. Check it on all the cylinders as a radical variation will probably mean the water jacket is partially blocked.
Exactly what temp to expect I don't know as it depends what temp the thermostat opens,but it'll be pretty obvious if it's overheating.
Need spares,consoles,consumables,hire,training or even a new boat?
