What is the “trim angle” of the engine?
Trim angle of an outboard or stem drive is the angle between the boat bottom and the propeller shaft formed by moving the engine/stem drive closer to the boat transom, called trimming “in” or “down” or “under,” or moving the outboard/stem drive further away from the boat transom called trimming “out” or “up.” When a boat is cruising on plane and the trim is adjusted so that the propeller shaft is parallel to the surface of the water, that is said to be running at “neutral” or “zero” trim. On outboards without power trim, this angle is adjusted by changing the hole in which the adjustable tilt pin is inserted. The term “trim” is generally used when referring to adjusting the outboard or stem drive within the first 20 range of travel. This is the range used while operating your boat on plane. The term “tilt” is generally used when referring to adjusting the outboard or stern drive further up out of the water.
Trim angle of an outboard or stern drive is the angle between the boat bottom and the propeller shaft formed by moving the engine/stern drive closer to the boat transom, called trimming “in” or “down” or “under.” Moving the outboard/stern drive further away from the boat transom is called trimming “out” or “up.” When a boat is cruising on plane and the trim is adjusted so that the propeller shaft is parallel to the surface of the water, that is said to be running at “neutral” or “zero” trim. With power trim, this angle is adjusted by a switch located on the control handle.
