Trim Tabs
This vessel is equipped with powered trim tabs
(see Figure 3.11.2). The trim tab electrical circuit
is protected with a 20 amp fuse located inside
the console storage/head. Trim tabs assist with
leveling the vessel when there is uneven weight
distribution or strong cross winds. Trim tab use may
also increase operator visibility, particularly during
initial acceleration. An untrimmed boat reduce fuel
economy and increase wear on the engine.
Operation
The trim tabs are controlled by rocker switches
located at the helm (see Figure 3.11.1). Short
momentary bursts of the rockers will achieve proper
attitude of the hull. Using the trim tabs will:
• Level the boat fore and aft, port and starboard
• Reduce steering system resistance
• Increase speed
• Reduce strain on the engine.
• Provide a smoother, more stable ride.
Visibility from the helm station may be limited,
use of trim tabs may be necessary to maintain
adequate visibility in some running conditions.
Avoid serious injury or death from collisions.
Maintain a lookout as required by USCG
Navigation Rules.
