Closed-loop cooling system
Efficient, compact reliability
Another Sea-Doo exclusive, the Closed-Loop Cooling System (CLCS) uses coolant to keep the engine running at ideal temperatures. Unlike competitors, this technology prevents corrosive saltwater and damaging debris from entering the engine, for increased reliability, longevity and peace of mind. Offered as an expensive upgrade on traditional inboard engines, CLCS comes standard on all Sea-Doo models.
