Re: engine exhaust high temp alarm Sea Chest Clog Alarm

I bought one from NASA, the boat instrument manufacturer. Cost @£82.00 including sensor which cable ties to the exhaust pipe. Easy to fit.
In Denmark last summer I neglected to turn the raw water seacock back on after cleaning out the strainer. Motored to fuel berth and filled up, started the engine again and within 15 seconds the exhaust alarm reminded me of my error! Saved my raw water pump impeller and seals plus a load more serious stuff. Should be a standard fitting for any boat especially in a weed prone area.
