🏁 Extends the factory trim range for more bow lift

More trim. More bow lift. More control over your setup.

Unlock extra trim adjustment with the RoosterGT Yamaha Max Trim Kit. Designed for compatible Yamaha WaveRunners, this aftermarket upgrade extends the factory trim range so you can run a more aggressive bow-up position.

Built around custom-manufactured aluminum components, it is made for riders who want to take their ski setup further.

How it works

Your WaveRunner's trim changes the angle of the jet nozzle. Trimming down keeps the bow low for acceleration and stability. Trimming up raises the bow. The Max Trim Kit extends the upward range past the factory limit, without touching the engine.

What it does not do

  • It does not add horsepower or RPM.
  • It does not guarantee a higher top speed.
  • It does not replace the jet pump.

RoosterGT. Engineered for performance. Built for the water.

What's in the box

  • Reduction nozzle wedge
  • Trim arm extension
  • Pre-shortened trim rod with solid stoppers
  • Mounting hardware

Installation

Bolt-on install with the parts in the box. The rod comes pre-shortened with solid stoppers, so there is very little adjusting. Follow the installation instructions closely, and email us if you get stuck.

Fitment and safety

Fits selected Yamaha WaveRunner models with adjustable trim, not every Yamaha. Email us your model and year to confirm fitment.

More upward trim changes how your ski handles. Too much bow-up trim can reduce stability and steering, especially at high speed or in rough water. Get used to the new range in calm water first.

Questions, answered

Still unsure if it is right for your ski? Email us and we will help.

What does the Max Kit do?

It extends the upward range of your Yamaha's existing trim system, so you can raise the bow higher than the factory limit allows. It changes the nozzle angle range, not the engine.

Does it fit my Yamaha?

It fits selected Yamaha WaveRunner models with adjustable trim, not every Yamaha. Email us your model and year and we will confirm fitment before you order.

Will it make my ski faster?

No. It does not add horsepower or RPM, and it does not guarantee a higher top speed. What you get is more trim range and more bow lift.

What is included?

A reduction nozzle wedge, a trim arm extension, a pre-shortened trim rod with solid stoppers, and the mounting hardware to complete the install.

Do I need to cut, weld or fabricate anything?

No. The kit bolts on with the parts in the box.

How hard is the install?

It bolts on with the parts in the box. The rod comes pre-shortened with solid stoppers, so there is very little adjusting. Follow the installation instructions closely, and email us if you get stuck.

Does it change how my ski handles?

Yes. Too much bow-up trim can reduce stability and steering, especially at high speed or in rough water. Get used to the new range in calm water before you push it.

More trim. More bow lift.
