Engine/Transmission Oil Thermostatic Control

Traditionally engine or transmission oil is continuously run through a cooler or heat exchanger to prevent the engine or transmission oil from overheating. Obviously this system works well but it does not compensate for the variable involved such as the water temperature your boating in, the size and efficiency of your coolers or how long it takes you to warm up your engine to bring it to proper operating temperature.

By installing a remote oil thermostat the oil will bypass the cooler until it reaches a pre-determined temperature at which point it will internally open and begin flowing the oil through the cooler to maintain a constant oil operating temperature. The Hardin Marine Xtreme oil thermostat can either be remotely mounted with 2 stand-off bushings or it can be connected directly to the oil cooler or remote filter head with a custom Hardin Marine coupler fitting.
