Sensors, encoders and controllers for Yamaha outboards
Sensors and encoders record physical values in the engine and convert them into electrical signals. These signals are passed on to the engine control unit or display instruments so that operating states can be monitored and engine functions controlled.
Typical sensors in outboard engines
Different sensors are used depending on the engine series, for example
-
Engine temperature sensor
-
Air temperature sensor
-
Throttle position sensor
-
Pressure sensors in the intake system
-
Trim position sensor
These sensors provide measured values for engine management, injection system and warning indicators.
Encoders for display instruments
Encoders are often used to transmit measured values to instruments. One example is the trim position sensor, which measures the angle of the outboard engine and forwards the information to the trim display in the cockpit.
Temperature or pressure sensors can also provide signals for instruments or warning systems.
Voltage regulator and rectifier
The voltage regulator is part of the electrical system of an outboard motor. During engine operation, the generator or stator generates electrical energy. The regulator ensures that this voltage is limited to a stable level so that the battery and on-board electronics are not damaged.
Many systems combine rectifier and voltage regulator in one component that converts alternating current from the generator into direct current for the battery.
Selecting the right spare parts
Sensors, encoders and regulators are selected using technical engine data:
-
Yamaha engine series
-
Engine power (hp)
-
Year of manufacture
-
Yamaha part number
Electrical components differ depending on the engine generation and engine management system.
