What is the wading depth of an EFI scooter motorcycle?
2 Answers
The wading depth of a scooter motorcycle is generally below the height of the exhaust pipe outlet. At this height, water immersion is completely safe. Since water does not enter the engine and does not even exceed the chassis height, you can generally start and drive the engine with confidence. Special reminders when wading: If slipping or idling occurs while wading, stop and turn off the engine immediately. If the motorcycle sways left and right and does not move forward, do not let the engine stall in the water. Solution for a flooded battery: It is recommended to go to a professional repair station and use a battery hydrometer to measure the specific gravity of the battery electrolyte. If the specific gravity is low, you can pour out the existing electrolyte, prepare a new electrolyte solution with the appropriate concentration as required, refill it, and then use a battery charger to recharge the battery.
The wading depth for EFI (Electronic Fuel Injection) scooters doesn't have a fixed value; it mainly depends on the vehicle's design and safety. Generally, the water depth should not exceed the wheel's axle position, such as the central point at the very bottom of the tire. The EFI system is particularly afraid of water, and the air intake is usually located below the footboard or near the front fork. Once the water level rises above this point, water can easily seep into the engine or electrical components, causing short circuits or damage to the ECU. I've seen a friend ride through water in such a scooter, and the EFI module failed directly, costing a lot to repair. A conservative suggestion is to avoid water deeper than 15 cm, roughly ankle-deep. But it's best to avoid it altogether since motorcycles have a high center of gravity, and if the puddle is deeper or the road is uneven, it's easy to tip over. Before heading out in the rain, I check the weather forecast and avoid waterlogged areas. If you must pass through, ride slowly and steadily, avoiding sudden acceleration or braking to minimize splashing. During regular maintenance, check if the waterproof seals are aging.
