5.7 CONTROLLING TRIM
Figure: Simultaneous outboard trim control
Trim refers to the angle between your transom and the outboard(s), and by extension the angle of
propeller thrust. Trim adjustment is provided to allow safe and efficient boating across varying speeds,
vessel loads and water conditions. As the operator, understanding the effects of trim and when
and how to make adjustments is key in maintaining vessel stability while optimizing performance
and fuel consumption.
Trimming out or UP raises the bow of your vessel. A bow-up attitude improves stability and results in less
drag, however if excessive, can result in propeller ventilation or porpoising (hopping through the
water), both of which are potentially dangerous.
