Call Us on 01902 730717Owning a WaveRunner means enjoying speed, fun, and freedom on the water but it also comes with the responsibility of regular maintenance to keep it running at its best.
Yamaha Waverunner Servicing
We specialise in both repair and maintenance, ensuring your Waverunner stays in peak condition. Our on-site service facilities are operated by fully trained, experienced, and insured engineers, who utilise the latest diagnostic tools and technologies to deliver top-tier service.
As part of our servicing, we will:
- Change your oil
- Flush the engine regularly
- Maintain your battery to prevent corrosion
Waverunner Winterisation
To prevent condensation and fuel degradation during winter storage, Yamaha Waverunner fuel tanks should be filled as much as possible to minimise air space. Additionally, treating the fuel with a stabiliser is crucial to maintain its freshness and prevent corrosion or gum deposits in the fuel system. We will advise on and service your marine engines for the winter.


Picking the right performance Waverunner is all about getting exactly what you want out of your time on the water. Whether you’re looking for a racer engine or just craving an adrenaline rush, a performance build gives you better power, speed, and handling. We fully customise our builds so you get a ride that’s just right for you and how you like to ride.
We provide:
Waverunner Performance Packages– Increase your levels of modification and performance gains with mapping, intake system upgrades, and exhaust system and more.
Custom Waverunner Builds– Significant modification to your waverunner will deliver you a unique high performance personal watercraft. This could include an engine rebuild, new components, hull modifications and upgrades to display.
Mapping– We will offer you Waverunner software, the Engine Control Unit (ECU), which controls various aspects, as the brain of your engine. Performance mapping, or ECU tuning, involves altering these factory settings to optimise the engine for increased power, torque, and responsiveness. This can be achieved through replacing it with a custom-developed map for the customer’s specific modifications.
By fine-tuning these settings, riders can experience improved acceleration, higher top speeds, better throttle response, and an overall more exhilarating ride.
Yamaha Outboard Servicing
We adhere to the highest standards of service and utilise genuine Yamaha parts in our outboard servicing. Our team of fully trained and insured engineers possesses in-depth knowledge of Yamaha outboards, ensuring your engine receives the precise care it requires.
Outboard Winterisation
Winterising your outboard is essential to prevent freezing damage to the cooling system, control mechanisms, and cables. For fuel tanks, filling them as full as practically possible and treating the fuel with a stabiliser prevents condensation, keeps the fuel fresh, and inhibits corrosion and gum formation.
