You are purchasing a modified oem thermostat housing with a 160f thermostat installed, this is a good alternative for those looking for extra cooling without having to install a full open loop kit , the stainless steel clamp and the 4 rivets are just for added peace of mind, This can extend the life of the engine by maintaining the proper engine temperature and allows it to produce the horsepower it is capable of. A properly functioning thermostat is a must have item on a watercraft that is operated in warm water climates, the oem thermostat is rated at 180F and can peak up to 205f in the hot summer months, with the 160f it will remain well under 180-185 under full load.

* if you mail back the old thermostat housing we will refund you $50 from the purchase price .
