Four-Stroke Jet Ski Winterization Guide
Winterize your 4-stroke jet ski the right way — from a shop that does this every single day.
This 7-page step-by-step guide from Odyssea Jet and Prop Shop (Ocean Pines, MD) walks you through the complete off-season winterization for Yamaha, Sea-Doo, and Kawasaki 4-stroke PWCs:
- Fuel system: stabilizer, fill level, circulating treated fuel (including Sea-Doo's 60-second hose rule)
- Engine oil & filter change, and why old oil can't sit all winter
- Cooling system flush and purge — open-loop and closed-loop (Sea-Doo) covered
- Fogging the cylinders to stop internal corrosion
- Battery removal, cleaning, and smart-tender storage
- Final wash, wax, and storage
Includes a printable checklist so you can track every step in the garage, plus a companion video walkthrough link — watch the job done step-by-step.
Written by working PWC technicians. Skip the $300+ shop bill and protect your investment yourself.
