US Patent 6964259 Nonadjustable outboard motor throttle linkage

A throttle linkage for use with an internal combustion engine is disclosed which connects a throttle actuator to a throttle assembly. The throttle linkage is nonadjustable and interacts with a plurality of throttle stops integrally formed with an engine block. Such an arrangement prevents tampering in advanced two-stroke engines and ensures emission output at a level well below that allowed.
