How a Combined Throttle/ Gearshift Lever Works
ENGINE CONTROLS Bow Stern
Remote throttle and gearshift controls are located at the steering stations, and the most common type for propeller-driven watercraft is the dual-function control, with a single lever that combines throttle (speed) and gearshift (forward, neutral, and reverse gears). It usually has a feature that will disengage the gearshift, to allow you to increase the throttle when starting or warming up the engine. Another feature of many lever controls is not allowing the engine to be started unless the gearshift is in neutral. If nothing happens when the ignition key is turned on, check to make sure the lever is in the neutral position. When shifting from forward to reverse or reverse to forward, pause briefly in neutral (do a 1-2-3 count) to prevent possible damage to the gears.

Throttle only button - push in when lever is in neutral position to increase throttle while in neutral.
Using a Throttle Control - Trim and Tilt Control On stern drives and many outboard motors (typically above 25 hp) and jet drives, the angle of the drive unit to the boat can be changed (trimmed) while the boat is underway to achieve better performance. This is usually done by hydraulic rams, which are activated by a toggle button normally located on the throttle control lever. These hydraulic rams can also be used to tilt the drive out of the water, when leaving the boat in the water or hauling out for storage or trailering. When operating in the trim range, the drive unit will move slowly; but once beyond the maximum UP trim position, the hydraulic speed will suddenlyincrease until the drive reaches its maximum tilt position.
