Review on Mercury Marine 143F Degree Thermostat Kit (75692Q2 & 75692T) - High Performance 2 Pcs for 135-150HP Outboard Motors by Duke Ballard

Revainrating 1 out of 5

Warning DO NOT BUY: Engine Cooling and Climate Control

They were supposed to open at 143 feet, my thermos in my boat rose to almost 200 feet and nearly destroyed my engine. I had to turn it off for about 20 minutes to let it cool and then head back to the pier and home. A piece of poor quality product. DO NOT RECOMMEND. I took the thermostat off the engine, put them in a pot and heated them to 143' and they didn't open at all.

Pros
  • Temperature range 143 degrees
Cons
  • Disappear
