Fitment & setup
Does it fit my Sea-Doo?
Use Find My Fit to check your exact model and year. A 1630 ACE engine or matching horsepower alone does not confirm the hull and exhaust layout. Sea-Doo Switch boat applications require separate GT40 confirmation.
What should I confirm before installation?
Confirm the current water box, inlet and outlet connections, retained hoses and clamps, and clearance. Send photos of the existing exhaust layout to support@gt40marine.com if the setup has been modified.
What is included and what else do I need?
This listing is for the shorty water box. Confirm the current packing list with GT40 before ordering; do not assume the rear-exhaust kit or other products shown elsewhere on the site are included.
