What is in your kit
Stage 1Yamaha ECU Reflash5.0 (6)Our proven WORX tune, done in house
Send us your stock GP SVHO ECU and we reflash it at WORX with our proven tune for the supercharged GP. We turn it around in 1 to 2 business days and it comes back in the same box as the rest of your kit. Tuned skis run on 98 octane.
Stage 1Solas YV-CD-13/18 Impeller5.0 (6)Pitched to suit the reflash
A stainless steel Solas impeller pitched to suit the reflashed ECU, so the pump makes the most of the extra rpm for stronger acceleration.

The Solas impeller tool for the Yamaha 1.8, so you can swap the impeller yourself.
Stage 11.8 SVHO Pump Wedge5.0 (8)Changes the angle of the pump nozzle for sharper hook up
Changes the angle of the pump nozzle which lifts the nose of the ski for sharper hook up and a better ride at speed.
Stage 1Yamaha Trim Extension4.9 (9)Increases trim range to lift the nose
Increases your trim range so you can bring the nose of the ski higher. Less hull in the water means reduced surface drag and a freer feel at the top end. Pairs with the pump wedge and fits 2015 onward RiDE models.
Handling KitGP1800 Intake Grate5.0 (1)Holds the water at speed
Holds water in the pump at high speed and through rough water, reducing cavitation when you are pushing hard.

Power KitYamaha Oil Catch Can5.0 (3)Catches oil vapour before it reaches the intake
Catches oil vapour from the engine breather before it can find its way back into the intake, keeping the supercharger and intake cleaner.
Power KitAir Filter with Breather Kit4.8 (6)More air, less restriction. Matched to your ski year
A higher flowing air filter so the engine can pull in more air, plus a filtered breather to replace the factory setup. We send the version that matches your ski year.
Power Kit2018+ SVHO Ribbon Remover5.0 (5)Opens up the intake path
Takes out the restrictive factory ribbon in the intake so air flows more freely to the supercharger.
Power Kit1.8L Cooling Kit5.0 (4)An extra water line straight into the block. Suits 2021 to 2026 GP SVHO
Adds an extra water line from the jet unit that feeds directly into the Yamaha 1.8 engine block. That extra cooling significantly lowers engine temperatures under load, which matters once the engine is tuned and on long, hot runs. Cooler running means a more reliable engine that keeps performing.
