The AquaTrax F-12 and F-12X Personal Watercraft (PWC) were developed with design goals of excellent driveability and environmental suitability superior to the existing 2-stroke engine PWCs. A 4-stroke engine and turbo charger were installed for the first time in PWCs. As a result, they passed the EPA 2006 emission regulation and the CARB 2004 emission regulation for the first time in PWCs, and driveability exceeded that of the existing 2-stroke engine PWCs. The turning ability of these PWC, like that of a motorcycle, was realized through a newly developed water jet pump suitable for the characteristics of a 4-stroke engine, and the hull bottom of Honda’s original shape. Thus, the level of existing PWCs was changed completely.
