information on trim tab adjustment. Torque induced list can also be corrected by shifting the load in 
your boat. Twin engines, when counter rotating, cancel the torque and no correction is required. 

 
Trim 

The power trim system allows the operator to raise and lower the drive unit or motor throughout an 
infinite number of settings between its upper and lower limits. For every throttle setting there is a 
trim setting that will yield optimal speed, stability or maneuverability. 
For most conditions the best all-round performance is obtained when the bow of the boat is slightly 
out of the water. 
General trim down (or "in") characteristics are: 

 

Starting position for best acceleration to plane. 

 

Lowers bow in the water providing better stability and ride in rough water. 

 

Reduces boat speed and economy due to increased drag of hull and drive. 

 

More spray over bow. 

General trim up (or "out") characteristics are: 

 

Raises the bow of the boat in the water, resulting in less hull in the water. 

 

Greater speed and economy for a given throttle setting. 

 

Greater maneuverability (provided prop does not ventilate during the    

   

maneuver) 

 

In excess, the reduced stability can lead to bouncing, porpoiseing and    

   

propeller ventilation. 

In addition to providing ideal boat performance, the power trim enables the motor or drive unit to 
be raised (tilted up) for trailering, beaching, and launching. 
The electric motor that drives the hydraulic pump is protected by an internal thermal circuit breaker 
that interrupts the power when overheated. Avoid continued pressure on the switch after the unit 
has reached the limits of travel (you can hear the difference in sound as the pump strains against the 
increased load).
