How does the Seadoo cooling system work?

The Sea-Doo cooling system works differently from any other PWC cooling systems on the market. Using closed-loop technology, a special coolant fluid is circulated around the engine in a closed system, which is cooled down by a heat exchanger (ride plate), placed on the bottom of the Sea-Doo’s hull.

What is Seadoo closed-loop cooling system?

Closed-loop cooling system (Sea-Doo ONLY) works much the same as an open loop system but instead of having water flow into the engine to cool it, antifreeze is used instead. The antifreeze is circulated through the engine than to a ride plate.

What causes a Sea Doo to overheat?

The most common reason why a jet ski overheats is a clogged cooling system or cavitation in the pump. Other possible causes are the lack of engine oil, clogged oil system, or carb issues.

Is it OK to run a Seadoo out of water?

Yes, you can run your jet ski when it’s out of the water and already on the trailer. Warning: You can only run your jet ski for 10 seconds maximum on land. Jet skis are designed to run in the water, not on land. The water intake cools the engine and if you leave it running for too long, you risk overheating the engine.

Is closed loop cooling better than open loop?

A closed loop cooling system is typically more intricate vs an open loop system, but it can still be a very effective cooling method. Similar to open loop, closed loop cooling uses surrounding water to cool off the engine. The main difference is that the water never enters the watercraft.

How do you fix a jet ski that is overheating?

To fix an overheating jet ski you should shut the engine down, and tow it back to the dock. First, inspect and clean the jet intake, pump, and the cooling system. Attach it to a garden hose and flush the cooling system for 2 minutes.

What temperature should a Seadoo run at?

What Temperature Should A Seadoo Run At? I would consider the Candoo or Buds Max screen shots useless. Many of these high temperatures were likely caused by flushing. It is recommended to use a temp between 160 and 180 degrees Fahrenheit for optimal performance.

How long can you run Seadoo on hose?

A jet ski can be run out of the water for about 15 seconds. If a jet ski is hooked up to a water supply, like during flushing, it can be run for about 90 seconds. You want to avoid going over 90 seconds when hooked up to a water supply as certain components are not being cooled.

Are Sea Doos closed loop cooling?

While your Sea-Doo’s ROTAX engine features a closed-loop cooling system, similar to that found in an automobile to ensure a consistent, debris-free source of cooling liquid, that liquid is cooled as it’s passed through internal channels in the craft’s ride plate, the rectangular metal plate covering the jet pump.

How long do closed loop coolers last?

Usually just 1 – 3 years without any sort of maintenance. Of course, if properly taken care of, meaning cleaned and flushed on a regular basis, even a custom setup can go toe to toe with an AIO and beyond.
