Rotax Catalyst Delete Kit
This kit allows you to delete the Catalyst from any vessel with a Rotax engine. With this kit, you can eliminate the catalyst and relocate the O2 Sensors. This kit is pretty much Plug and Play. **NO MODIFICATION TO ECU OR WIRING HARNESS** There are only 2 things that you will need to "figure out" is connecting the exhaust hose from waterbox to resonator / exhaust outlet, depending on how it is setup on your boat. The 2nd is re-arranging the cooling lines. We can give you a diagram on how it needs to be done, but you may need to purchase some hose depending on the exisiting layout of your boat. PLEASE NOTE, THAT YOU NEED ONE KIT PER ENGINE. with a Twin Engine Boat, you need to order 2 kits. This system works on any Rotax powered Scarab, Chaparral Vortex, Seadoo Switch, Williams Tender, ABJet Tender...etc ..etc... All of these products, minus our custom designed ones, are OEM BRP Rotax Components. Deliveries average about 7-10 days from the moment the order is placed.
