Had a problem ( now solved) of our Genset loosing raw water to the rubber exhaust and cooking it, twice. Now I’ve installed a duel sensor for head temp and nest temp so we can get an early warning of flow issues. Also now have one monitoring the mains exhaust temps to protect their rubber hoses too.

Temp in the photo is 36 degrees as I had only just welded the nut to the stainless exhaust section to secure the sensor.

Having worked on a tourist boat that had the fiberglass exhaust catch fire ( total loss of vessel) it’s not an experience I want to repeat!

Cheers ?
