The Watercraft Journal test rides RIVA Racing’s maniacally-fast Stage III kit-equipped 2018 Sea-Doo RXT-X 300. Starting with a stock 2018 Sea-Doo RXT-X 300, RIVA Racing throws on its proven Stage III kit to aptly unlock all of the power potential in the venerable ACE 300 engine and unlock what can be done with the new ST3 platform. We were wowed with this package as it gives the enthusiast all of the power and neck-snapping acceleration that you’d expect for the hardcore racer. The thrust comes on so dang hard we literally launched the ski completely out of the water – that is until we engaged the Sea-Doo’s factory Launch Control – and then BAM! We were off and running all the way to 83mph. And so can you.
Here’s a complete list of parts:
