The Seabob F9S is the high-performance model in the third-generation F9 series, engineered by CAYAGO AG and designed by Studio F.A. Porsche. With 84TP of thrust, the Driving Stability System as standard, and a 3.6kW motor, the F9S is built for riders who want the full capability of the platform without compromise.

Design by

Studio F.A. Porsche

For the designers at Studio F.A. Porsche, design is a symbiosis of form and function. Every surface angle on the F9S hull influences water behaviour at speed, resulting in a watercraft that earns its shape, not just wears it. Developed in direct collaboration between CAYAGO engineers and the Porsche design studio, the F9S takes the same hydrodynamic foundation as the F9 and dials up the performance and specification throughout.

Sport Mode

84TP. Pure Sportiness.

The F9S runs a 3.6kW motor producing 84TP of thrust, 40% more than the base F9. Activate Sport mode with a single sensor switch and you have maximum motor output on demand. The digital thumb throttle gives infinitely variable speed control with no step changes or lag, just immediate, predictable response across the full power band. The E-Jet propulsion system generates maximum thrust with minimal energy draw, zero emissions, and low operating costs.

Dive Mode

Below the Surface.

Switch to Dive mode and throttle sensitivity increases for precise, comfortable underwater navigation, giving finer control at depth without sudden power surges. A built-in depth sensor triggers automatic cut-off at 3.0m (10ft), and the electronic control system can be pre-set to a maximum diving depth of 25m (82ft). Steering is handled by shifting body weight, keeping both hands on the grips and both eyes on what's below.

Driving Stability System

The F9S includes the Driving Stability System as standard. The entire wing system mounted at the jet nozzle, combined with extractable rear-side wings and two foils on the underbody, work together to create highly stabilising buoyancy forces across all riding modes.

The result is a noticeably more planted, confident ride at speed and in turns, particularly in choppier water where the base F9 requires more active rider input to maintain stability.

Patented Technology

E-Jet Power System

The worldwide patented E-Jet Power System works on the principle of water displacement. Water is drawn in by a high-speed impeller and forced out through the jet channel under pressure, generating maximum thrust with minimal energy draw.

High-grade titanium, magnesium, and ceramic-coated components keep weight tight at 25.9kg while maintaining the durability needed for saltwater environments. The drivetrain is emission-free with extremely low operating costs compared to combustion alternatives.

Three Riding Modes

Normal

Balanced power delivery for surface cruising and casual water exploration. Ideal for relaxed sessions and sharing with guests.

Dive

Throttle sensitivity increases for precise underwater navigation. Finer control at depth without sudden power surges.

Sport

Maximum 84TP output at the touch of a sensor switch. Full thrust for high-speed surface runs where the F9S really separates itself.
