Use the Sea-Doo operator guide for your exact model and year to plan winter storage. Flushing, engine-running limits, internal lubrication and cooling-system protection depend on the machine. Have the correct guide open before starting work.
Start with the correct instructions
Find your model and year in BRP's operator-guide library. Read the storage and maintenance sections together, including the required tools, products and safety instructions. Sea-Doo's winterization overview is a useful planning reference; the instructions for your exact watercraft determine the procedure.
Make a storage checklist
Check the manufacturer's instructions for fuel treatment, engine oil and filter service, internal engine lubrication, exhaust and cooling-system protection, battery care, cleaning, corrosion protection and the storage cover. Complete the items that apply to your model and record the date and work performed.
Confirm changes to the machine
If the watercraft has aftermarket cooling, intake, exhaust or other modifications, identify the exact installed parts before using the factory storage procedure. Confirm any additional requirements with the component manufacturer or a qualified service shop.
Get help before starting
If the correct procedure or installed hardware is unclear, arrange service with a Sea-Doo dealer or qualified shop. For questions about an installed GT40 part, send support@gt40marine.com the exact SKU, watercraft year and model, and photos of the installation.
