How do I winterize a Sea Doo Jet Ski? It's a 2006 185hp.?

Answer 1

Winterize your Jet Ski by placing it on your trailer in
such a manner that the water intake for the engine
is accessable to you. Place a hose with a suction cup
onto the engine cooling water intake (if engine is
water cooled). Take the other end of the hose and place it in a bucket of 50 - 50 Antifreeze and Water. Manuver
the bucket so that it is about the same height as the
engine. Get all the air out of the hose. Crank the engine.
Turn off the engine when the bucket is almost empty.
Mission accomplished.

If the engine is air cooled... no antifreeze is required
for the engine cooling system. What you have to do is
make sure that there is no water in the engine pump
- thrust system. You can do that by cranking the
engine for a moment while the Jet Ski is on the trailer.
Only do this for a moment. One quick twist of the
throttle. All the water inside should be expelled.

Check the drain plug and make sure there is no water
inside the hull.
