Gearcase Trim Tab

Gearcase trim tabs are components used in gasoline reciprocating engines, specifically those that are not used in aircraft. These trim tabs are part of the gearcase, which is responsible for controlling the pitch of the propeller. The trim tabs are adjustable surfaces attached to the gearcase that help fine-tune the pitch of the propeller blades, allowing for optimal performance and efficiency of the engine. They are crucial in maintaining the desired engine speed and power output. These gearcase trim tabs are classified under the supply class Gasoline Reciprocating Engines, Except Aircraft; And Components in the supply group Engines, Turbines, And Components.
