Smaller boats have only one outboarder. When using two outboarders, a motor is often associated with a left and a right-hand rotation propeller. By using the opposite direction of rotation, the boat has a neutralized screw effect and improved directional stability.
Outboarders are primarily mounted on the stern of the boat, or in an engine bay close to the stern. The engine can often be pulled or tilted at an angle, so that the underwater part is not damaged during transport or landing. If outboard motors are mounted to swivel to the side, the boat can be controlled by the pivoting effect, rather than by a rudder. Therefore, most boats, which have an outboarder, don't have separate rudders.
Outboarders are manufactured for attachment to different boats with different lengths of shafts. The length of these units ranges between normal or short shaft
(15") and long shaft
(20").The required shaft length is entirely dependent on the height of the stern. When attaching an outboard motor to a boat without a matching stern length, handling of the boat worsens.
Smaller outboarders are often equipped with a recoil starter
and steering tiller
, with which the motor is rotated in its bracket, around its vertical axis according to either port or starboard. A small integrated tank
is usually located in the motor housing, it can also be connected to separate outboard tanks
, which are often equipped with a level indicator and a reserve fuel chamber.
Stronger outboarders feature electric starters
, most come with loading devices for the starter battery and the supply of electricity being consumed on board.
In inland areas
, persons aged 16 and over
may drive recreational craft up to a length of 15 metres without a licence
, provided that the net power of the engine does not exceed 11.03 kW (15 hp
) and that it is not used commercially. The only exception to this regulation is on the Rhine. Due to international regulations, a driving licence is required for a net power of more than 2.68 kW.
, sport boats up to a maximum net power of 3.68 kilowatts (5 hp)
may be operated without a licence, irrespective of age
, as long as they are not used commercially. With a net power of 3.69 to 11.03 kW, the skipper must also be at least 16 years old to be able to operate a pleasure boat at sea without a licence for private purposes. There is no length limit here for recreational craft.
Of course, this regulation not only applies to smaller boats with outboard engines, but also to motorboats or sailboats with inboard diesel engines
. In the run-up to and after the introduction of regulatory amendments to rules regarding recreational craft in October 2012, some massive objections and safety concerns were expressed. Here, we can only ask that hobby skippers act responsibly
to "sensibly" handle stronger powered engines. In some situations, the new regulation can even improve safety
, as: "Many boats were dangerously underpowered in crisis situations with a 5 hp motor".
