How to winterize Seadoo Challenger Boat

I’ve been doing this for 3 seasons and it’s pretty simple. You just need a few things.
Plan:
1. Stabilize fuel
2. Run RV antifreeze through intercoolers
3. Blow out excess RV coolant (might not be completely necessary)
4. Fog engine cylinders

Great vid. Also it's good to run antifreeze through your bilge pump.

How long do you leave it sitting in the water during boating seadoo?
You use rv for the environment.
When do you change the oil?

Hey man. That boat sits for about 3 months in the water.
I use RV environment liquid
I changed the oil last year. I have no idea when it was changed before I had it.
