Although less efficient than an open propeller, they are particularly useful in applications where the ability to operate in very shallow water is important.
Pump-jet propulsion is available as an option on most outboard motors. As these engines do not use permanent magnets, they require less maintenance and develop more torque at lower RPM. The advantage of the induction or asynchronous motor is the power transfer to the rotor by means of electromagnetic induction. With this setup, a motor can produce 10 kW output or more and is able to replace a petrol engine of 15 HP or more. Recently developed outboard motors are powered with an alternating current (AC) or DC electric motor in the power head like a conventional petrol engine. Most electric outboard motors have 0.5 to 4 kW direct current (DC) electric motors, operated at 12 to 60 volts DC. These are not to be confused with trolling motors, which are not designed as a primary source of power. In addition many small motor manufacturers have begun offering variants with power trim/tilt and electric starting functions so that they may be completely controlled remotelyĮlectric outboard motors are self-contained propulsory units for boats, first invented in 1973 by Morton Ray of Ray Electric Outboards. In this application, the motor is frequently installed on the transom alongside and connected to the primary outboard to enable helm steering. for trolling aboard larger craft, as small outboards are typically more efficient at trolling speeds.
to provide auxiliary power for sailboats.to power small craft such as jon boats, dinghies, canoes, etc.The smallest of these weigh as little as 12 kilograms (26 lb), have integral fuel tanks, and provide sufficient power to move a small dinghy at around 8 knots (15 km/h 9.2 mph)
KICKER MOTOR ON INBOARD BOAT MANUAL
These motors typically use a manual start system, with throttle and gearshift controls mounted on the body of the motor, and a tiller for steering. They are affixed to the boat via clamps and thus easily moved from boat to boat. Small outboard motors, up to 15 horsepower or so, are easily portable. These range from 2-, 3-, and 4-cylinder models generating 15 to 135 horsepower suitable for hulls up to 17 feet (5.2 m) in length to powerful V6 and V8 cylinder blocks rated up to 627 hp (468 kW)., with sufficient power to be used on boats of 37 feet (11 m) or longer.
KICKER MOTOR ON INBOARD BOAT PLUS
Generally 100 hp plus is linked to controls at the helm. Large outboards affixed to the transom using clamps and are either tiller steer up to approx 100 hp. A motorboat with an outboard motor attached to it Large outboards
