Let’s dive into the most common questions we get from our riders.

KOOTU Fuel Surfboard

1. What is the correct fuel mixture ratio?

To ensure optimal engine performance, use #95 above gasoline mixed with lube oil at a 30:1 ratio. This blend provides smooth power delivery while protecting the engine during high-speed sessions.

2. How long can I ride on a fully charged battery?

Although KOOTU surfboards are fuel-powered, they include electronic components that require charging. A full battery charge typically supports up to two days of play, depending on your riding frequency. For best performance, charge the battery once every day after use.

3. How long does it take to fully charge the battery?

The charging time is approximately 5 hours from 0% to 100%. Make sure to use the provided charger and avoid overcharging to extend battery life.

4. What is the engine compression ratio?

The engine features a 9.2 compression ratio, offering a good balance between power and fuel efficiency. This allows the surfboard to perform reliably even under various load conditions.

5. What is the normal engine pressure and water pull strength?

Engine pressure: 140 psi

Normal pulling force in water: 50–55 kg

These specs ensure a stable and powerful surfing experience, suitable for handling waves and long-distance gliding.

6. What rider weight is recommended?

The KOOTU fuel surfboard can reach up to 55 km/h under optimal conditions, as tested with a 140 lbs (63.5 kg) rider. We recommend riders under 90 kg (200 lbs) for best performance. Heavier riders may experience slightly reduced top speeds.

7. How do I adjust the carburetor?

Carburetor tuning is key to surfboard performance:

Tighten inward: Fuel mixture becomes leaner, speed increases.

Loosen outward: Fuel mixture becomes richer, speed decreases.

Adjust carefully to find your perfect speed-to-efficiency balance.

8. What is the standard idle speed?

In water (with resistance): 3500 rpm

On land (no load): 8000 rpm

Maximum no-load RPM: Up to 9000 rpm

These values ensure a smooth start and reliable acceleration in all conditions.

9. How often should I change the gear oil?

Proper gear oil maintenance keeps your motor running strong:

First 6 months: Change once

Afterwards: Once per year

Recommended oil: Synthetic 15-40W

Amount: 0.2L

Keeping up with this schedule will extend the life of your engine and gear system.

10. What is the average engine lifespan?

The KOOTU surfboard engine is built to last 800 to 1000 hours with regular maintenance. When the engine needs to be replaced, you can buy it directly from the official KOOTU website.

11. How much water does the pump discharge?

The integrated water pump can discharge 2 liters per minute, provided there is sufficient water. This helps with cooling and ensures efficient engine operation during long rides.
