[QUOTE="MuskyManiac, post: 50506, member: 381"] johnr, I know you have had problems with your Opti, but I think there was an issue with your HP/year class. My Opti has been bulletproof for me. Heat issue with my engine are either related to water pressure/impeller, thermostat, or poppet valve. I know you can damage an Opti running high RPM's if the engine is not hot enough. My thermostat opens around 138 degrees. Poppet valve will open around 2500 RPM's, bypassing the thermostat. The telltale lets me know water is running through the air compressor, but doesn't tell you much more. [/QUOTE]
