Adaptive Speed Control (ASC)
Similar to cruise control in a car, the electronics maintain the selected engine speed regardless of the situation.
Advanced Range Optimisation (ARO)
The electronic engine management system is designed to increase performance and reduce fuel consumption.
Advanced Sound Control (ASC)
ASC is a switchable (ultra-quiet or emphatically sporty) silencer system.
Anti-cavitation plate
The flat housing section above the propeller. The anti-cavitation plate guides the water flow and prevents air from being sucked in by the propeller, which would reduce its efficiency.
Operating hours counter
Electrically started, it counts and displays the operating hours of the engine.
Blast
The electronic engine management system automatically optimises the ignition timing and fuel/air mixture during acceleration to generate more thrust.
Bracket
Component with tommy screws or through bolts for attaching the motor to the boat transom.
Choke
Manually or electrically operated cold start device on the outboard motor.
Command-Thrust outboard
Motors with gear ratios and propellers designed for thrust rather than speed.
Digital Throttle & Shift
A system that actuates the throttle and gearstick digitally, i.e. electrically.
DOHC engine
Engine with two overhead camshafts (double overhead camshaft).
Double propeller
A left-hand and a right-hand propeller mounted on a shaft that rotate in opposite directions when travelling. The advantages are better course stability, better acceleration and lower fuel consumption.
Twist shifter
The transmission can be shifted into forward, neutral and reverse using the throttle twist grip on the tiller.
Rev counter
Display for checking the engine speed.
Speed limiter
An electronic component that prevents the motor from turning above the maximum speed specified by the manufacturer.
Drive-by-wire
Steering, throttle and transmission are electrically operated.
ECOmo
The electronic engine control system regulates the fuel-air mixture in such a way that fuel consumption and pollutant emissions are reduced.
Electronic Fuel Injection (EFI)
Electronically controlled petrol injection.
Single lever control
Remote control in which the gearstick and throttle are operated with the same lever.
E-starter
Motors that are started electrically.
Remote control
The throttle and gear shift are operated on the engine, i.e. the outboard motor itself, from the driving position.
Remote control
Wheel control with which the steering angle of the motor is determined from the driving position.
Shallow water position
A mechanism that allows the motor to be tilted and locked so far that it can also be used in shallow water.
Four-stroke engine
Four-stroke engine
Counter-rotating propellers
For boats with two engines, it is advantageous to use counter-rotating propellers. This means that the propeller of the left-hand engine turns to the left when travelling forwards and the propeller of the right-hand engine turns to the right.
Rectifier
Electronic component that converts current from the three-phase alternator into direct current, which is used to charge the battery.
Hand starter
The engine is started mechanically by hand.
Hydraulic steering
The steering angle of the engine is regulated via the steering wheel, a steering gear designed as an oil pump, lines and a hydraulic cylinder. Advantage: Hydraulic steering can be operated with less effort.
Jet drive
A drive in which an impeller driven by the engine draws in water under the bottom of the boat and expels it again via movable nozzles at the stern. Advantage: Jet drives can also be used in extremely shallow water.
Joystick piloting
Steering, throttle and gear shifting are electronically controlled via a joystick. Advantage: safe and very easy manoeuvring. Disadvantage: Joystick piloting only works on boats with twin engines.
Cavitation
Vapour bubbles imploding on the propeller surface. Constant cavitation, in which tiny metal particles detach from the surface, can destroy the propeller.
Weed-repellent propeller
Its specially shaped blades repel weed and seaweed from the propeller.
Lean burn system
Ensures the right fuel-air mixture in every situation, depending on the load.
Light connection
Connection for the power supply of the position lanterns on small motors.
Air cooling
Specially designed flywheels have a fan function to cool the motor.
Maximum Acceleration System
When the throttle lever is moved quickly, the ignition timing is automatically advanced, which is intended to improve acceleration from low speeds.
Mechanical steering
The steering angle of the motor is determined via the steering wheel and a sturdy Bowden cable (cable) from the driving position.
Mixing ratio
Expresses the ratio in which petrol and oil must be mixed for perfect engine lubrication in two-stroke engines.
Multifunctional instrumentation
Engine instruments that can show much more than just information about the engine and its surroundings on a display.
Emergency start
A rope wrapped around the flywheel that can be used to start smaller engines by hand.
Sacrificial anode
Zinc or magnesium "blocks" mounted in the underwater area and in the cooling system. Sacrificial anodes protect the motor from damage caused by galvanic corrosion.
Tiller
Folding lever with integrated throttle twist grip that moves the engine back and forth to steer the boat. Modern, larger engines sometimes have tiller with integrated ignition lock, gear lever and power trim.
Power-Tilt
Device with which the motor can be hydraulically tilted up and down beyond the trim angle.
Power trim
This allows the motor to be raised and lowered electro-hydraulically at the touch of a button while the boat is travelling, so that it is (almost) always in the optimum floating position.
Prime Start
Electronically controlled cold-start device.
Propeller diameter
The diameter of the circle described by the propeller blade tips during one revolution.
Propeller pitch
The distance (usually given in inches) that a propeller would travel in a solid material during one revolution.
Propeller hub exhaust
Exhaust gases and cooling water escape under water through openings in the propeller hub.
Propeller slip clutch
Connection between the propeller hub and the outer propeller housing. The "rubber coupling" slips if the load is too high and thus protects the gearbox.
Quickstop
The ignition is interrupted by a ripcord and the engine stops abruptly.
in-line engine
Engine whose cylinders are arranged in a row one behind the other.
Reverse lock
Mechanical holding device that prevents the motor from tipping up when travelling in reverse.
Shank length
The dimension (measured in mm) between the contact surface of the mirror mounting (bracket) and the anticavitation plate.
Shear pin
Metal pin (in propeller shaft and hub) with predetermined breaking point. If the propeller hits an underwater obstacle, the pin breaks. The connection between the propeller and shaft is released and the gearbox remains intact.
Selective direction of rotation
Depending on the switch position, one and the same motor can be operated both in the standard direction of rotation and in the opposite direction
Mirror height
Dimension (measured in mm) between the support point of the motor mount and the lower edge of the boat floor.
SOHC engine
Engine with an overhead camshaft (single overhead camshaft).
Spur
Housing part below the propeller. The spur protects the propeller in the event of grounding.
Standard propeller
Propeller supplied as standard by the manufacturer.
Symmetrical propellers
They generate the same thrust forwards and backwards.
Thermostat
Valve that regulates the cooling water flow depending on the engine temperature.
Tilt limiter
Electronic component that limits the tilt angle of the engine and thus protects the hull from damage.
Trim indicator
Instrument (power trim only) on which the tilt position (trim position) of the motor is displayed.
Trim bolts
The trim bolt can be used to change the angle of attack of the motor in relation to the boat's transom.
Trim fin
By adjusting (turning) the trim tab, which is often designed as a sacrificial anode, a boat that is travelling "freehand" into a right or left turn can be "trimmed" to go straight ahead.
Trim angle
Position of the motor in relation to the vertical. The correct trim position, which brings the boat into the optimum floating position, can only be determined by test runs.
Trolling system
Important for sport fishermen: the idle speed can be changed up or down in "50 rpm increments" at the touch of a button.
Translation of
The ratio of engine speed to propeller shaft speed determined by different sized gears in the gearbox.
VCT or VVT
Engines with variable valve timing (Variable Camshaft or Variable Valve Timing).
Four-valve technology
Engines with four-valve technology have two intake and exhaust valves per cylinder.
VETEC
VETEC varies the stroke and opening time of the intake valves under electronic control, thereby optimising the torque.
V-N-R circuit
The gearboxes of these motors can be shifted forwards, backwards and neutral.
V-engine
The cylinders of these engines are arranged in a V-shape. The number after the V indicates the number of cylinders.
Water cooling
To dissipate the heat, water is pumped through the engine's cooling ducts. A thermostatic valve controls the cooling water flow depending on the engine temperature.
Immobiliser
An electronic "remote control" ensures that the engine only starts when you give the "OK".
Two-lever gearstick
Remote control, equipped with one lever each for throttle and gearbox.
