3.6 Pump Control Module (PCM)

This is located in a dry area and can usually be found inside the center
console, in the area behind the dash, or in a compartment near the
engines or batteries. The PCM is always located close to the hydraulic
pumps. There will be one PCM on twin engine boats and two PCM's
on triple or quad engine boats. The PCM controls the steering and
joystick operation.

3.7 Hydraulic Steering Pumps
The hydraulic steering pumps supply pressurized fluid to the
SmartCylinders to steer the engine and are located near the PCM.
They can usually be found in a compartment
near the engines, the center console
or behind the dash. There is one
pump for each engine.
Note: these pumps look a lot like
the trim pumps that tilt the engines
but can be distinguishedby the
decal and the green/blue SeaStar
Electronic Power Steering Fluid.
The pumps have the steering
fluid reservoir and this is where
the fluid level is checked
and steering fluid is added.
