Maximum power

The maximum operating power of the outboard motor, expressed in kilowatts.

The practical value of motor power is described in detail in “Maximum power" is higher. Here we note that the kilowatt (derivative of watt) is just one of the units of power used in fact along with horsepower (hp); 1 HP ≈ 735 W (0.735 kW). Watts are considered the traditional unit for electric motors (see "Engine Type"), but for a number of reasons, outboard motor manufacturers use this designation for gasoline models as well.

Maximum pulling

The greatest traction force developed by the outboard motor. It is measured in kilograms: for example, indicators of 15 kg mean that the motor at maximum power pushes the boat forward with the same force with which a load of 15 kg presses on the surface below it. The recommended weight of the boat depends on this parameter (see below): the greater the weight, the “stronger” the motor must be in order to successfully move the boat through the water. The difference between deadlift and recommended weight may seem huge at first glance: for example, the mentioned 15 kg corresponds approximately to the recommended weight of 800 kg. However, this is not unusual, because the friction on the surface of the water is extremely small, and it does not take much effort to move the boat.

For a number of reasons, this indicator is indicated only for electric motors (see "Motor type").

Propeller screw

The design of the propeller supplied with the appropriate type of outboard motor (see above). In this case, the simplest division is used — by the number of blades.

This indicator actually refers to reference, and not practically significant, because. the practical characteristics of the propeller depend not only on the number of blades, but also on their shape and length, and a number of other indicators (power, thrust, etc.) affect the general characteristics of the motor. In addition, manufacturers tend to select propellers based on the best match with the desired capabilities of the motor.

Transom height (deadwood)

The height of the transom of the boat for which the motor is designed. This parameter is also called “leg length” (meaning, of course, the “leg” of the motor itself, and not the boat).

The transom is a part in the stern of the vessel, designed to mount the motor. The length of the motor leg must match the dimensions of the transom, otherwise the propeller will be at an off-design depth, which is fraught with problems in operation and loss of power (regardless of whether it is too deep or too shallow). The height of the transom, usually, is indicated in the documents for the boat itself — it is from these data that one should proceed when choosing a motor according to the length of the leg.

Weight

The total weight of the outboard motor. This parameter is indicated, usually, only for the unit itself, without taking into account the fuel in the tank and the tank itself (if it is external, see "Fuel tank"), as well as additional equipment. Motor weight data can be useful in order to estimate the overall balance of the boat and the change in its payload capacity.
