ABSTRACT:
A watercraft powered by a pair of jet propulsion units each having reverse thrust buckets that are controlled by pedals positioned in the operator's compartment. The pedal control is such that both reverse thrust buckets can be operated by a single foot of the operator for reverse thrust operation and braking or so that each pedal may be operated independently for abrupt turning maneuvers. An interlock system is provided so that the engines for the jet propulsion units cannot be started unless the reverse thrust buckets are in their neutral positions and a detent mechanism is provided for holding the pedals and the reverse thrust bucket in this neutral condition.
