Changed the impeller and good stream out the tube
was wondering if I removed the thermostats if it would run cooler. This week was 105 degrees on water. The water temp was in 80's maybe its too hot to cool engine and stop alarm from sounding |

Nope - operating temp for the engine is 140-170 degree range, so unless you are running in water that has a temp of about 120 degrees and you do nothing more than putt around you need the thermostats.
There is no water that you can run your motor in that will be TOO HOT to allow your motor to properly cool if it's components are working as they should - unless of course you use your hot tub as a test tank... |
