Video: GreenHulk And RIVA Take Aim At Heat Soak With GEN-3 Yamaha Power Cooler

Anyone pushing big boost on a Yamaha SVHO or SHO platform knows the enemy isn’t always horsepower — it’s heat.

The factory intercooler on these machines does a respectable job in stock form, but once riders start stacking performance upgrades — higher boost, ECU tuning, freer-flowing exhaust — intake temperatures can climb quickly. That heat buildup, known as heat soak, robs power and consistency. The longer and harder the craft is run, the hotter the intake charge becomes, and the less power the engine can produce.

That’s where GreenHulk PWC Performance Store and RIVA Racing step in with a solution designed specifically for riders chasing reliable high performance.

The RIVA GEN-3 Yamaha Power Cooler, available through GreenHulk, replaces the restrictive OEM intercooler with a massive high-efficiency cooler core engineered to keep intake air temperatures under control — even under sustained boost and high ambient temperatures.

According to RIVA, the GEN-3 Power Cooler can reduce intake air temperatures by an average of 50°F compared to stock, helping deliver up to 20 peak horsepower gains while maintaining consistent performance across the entire RPM range. Cooler air is denser air, and denser air means more oxygen available for combustion — the foundation of reliable power on the water.

At the heart of the system is an oversized cooler core rated to support engines producing up to 600 horsepower, making it suitable not just for mild upgrades but also for serious high-output Yamaha builds.

Key Performance Advantages

  • Up to 20 horsepower gain over the OEM intercooler
  • Intake temperatures averaging 50°F cooler
  • Massive cooler core rated for up to 600 HP builds
  • Helps eliminate power loss caused by heat fade
  • Designed for minimal pressure drop and maximum airflow

Beyond performance, the GEN-3 Power Cooler is built with durability and serviceability in mind. A high-strength corrosion-resistant coating protects the cooler core in harsh marine environments, while a replaceable sacrificial zinc anode adds an extra layer of corrosion protection.

Maintenance is also simplified thanks to a quick-release flushing system, allowing riders to easily rinse the cooler after saltwater use. The entire unit mounts using shock-isolated rubber mounts and stainless hardware to withstand the pounding that comes with aggressive riding and racing.

For riders looking for additional supercharger protection and throttle response, RIVA also offers a version that includes an integrated 50mm TiAL blow-off valve, helping reduce pressure spikes and improve drivability.

Available Configurations

With TiAL Blow-Off Valve
SKU: RY17081-PC-TV / RY17120-PC-TV / RY17160-PC-TV

Without Blow-Off Valve
SKU: RY17081-PC / RY17120-PC / RY17160-PC
Ideal for setups already running an external TiAL BOV or block-off configuration.

Compatible Yamaha Models

  • 2008–2016 FX SHO
  • 2009–2016 FZR / FZS
  • 2014–2018 FX SVHO
  • 2019+ FX SVHO
  • 2017–2018 GP1800R SVHO
  • 2019–2020 GP1800R SVHO
  • 2021+ GP1800R SVHO

Because the GEN-3 Power Cooler dramatically increases cooling capacity, RIVA also recommends pairing it with their Pro-Series Engine Cooling Upgrade Kit to ensure the cooling system can keep up with the added performance.

For riders building high-horsepower Yamaha SVHO or SHO engines, managing intake temperatures isn’t just about making more power — it’s about keeping that power consistent lap after lap, ride after ride.

And thanks to GreenHulk PWC Performance Store, the upgrade that solves the heat problem is just a click away.
