Description
Take control of cooling on your high performance Sea Doo 4TEC or 1630 ACE platform with this billet aluminum 160 degree high flow fail safe thermostat kit designed for open loop conversions. Featuring a new 7 8 inch neck, each end of the housing is precision CNC machined from a single piece of T6 6061 aluminum and finished in a tough black anodized coating to combat corrosion in harsh marine environments. The fail safe thermostat begins to open at 160 degrees Fahrenheit and is engineered to lock in the open position in the event of overheating, ensuring maximum coolant flow when you need it most.
- Designed for Sea Doo 1503 Rotax 4TEC 130 155 215 255 260 engines and 300 HP 1630 models running open loop cooling systems.
- Billet aluminum housing with 7 8 inch neck provides a strong, leak resistant connection that stands up to vibration and repeated service.
- Includes stainless steel bolts and two high quality o rings for a long lasting seal and straightforward installation on compatible models.
- Fail safe thermostat design protects the engine by remaining open if an overheat situation occurs, promoting maximum coolant flow instead of trapping heat.
- Ideal upgrade for modified skis running higher boost, aggressive tunes, or race use where consistent temperatures and cooling efficiency are critical.
- Made in the United States with attention to detail that matches the expectations of performance Sea Doo owners.
Pair this thermostat with a properly designed open loop cooling layout to keep your Sea Doo running cooler, safer, and more consistent during long wide open throttle sessions.
