Document Type and Number:
Japanese Patent JP2963492
Kind Code:
B2
Abstract:
A throttle opening limiting system is provided for a marine propulsion unit comprising a throttle, a manually operated throttle control device and an intermediate linkage arrangement operatively connecting the manually operated throttle control device to the throttle. The intermediate linkage arrangement further comprises a means for setting a distinct and different maximum obtainable throttle opening position for each of a forward, a neutral and a reverse operative state of the marine propulsion unit. The throttle opening limiting system is fully openable in the forward operative state, is limited to an intermediate position in the reverse operative state, and is limited to a smaller opening position in the neutral operative state than the intermediate position of the reverse operative state. The throttle opening limiting system is capable of preventing overspeed engine rotation in both the neutral and reverse transmission operative states, while nevertheless securing the necessary thrust required for proper running of the craft in the reverse operative state.
