Page "Outboard motor" Paragraph 5

In order to eliminate the chances of hitting bottom with an outboard motor, the motor can be tilted up to an elevated position either electronically or manually.

This helps when traveling through shallow waters where there may be debris that could potentially damage the motor as well as the propeller.

If the electronic motor required to move the pistons which raise or lower the engine is malfunctioning, every outboard motor is equipped with a manual piston release which will allow the operator to drop the motor down to its lowest setting.
