After all, there are boat motors of relatively reliable power, for example, 3 hp. There are a lot of suitable electric outboard motors. Recall that the minimum acceptable power is ¼ of the maximum permitted power indicated in the technical characteristics of the inflatable boat, for example, with a maximum allowable power of 3.3 hp. Given that electric motors are chosen for inflatable boats designed for low-power motors (usually up to 3.3 hp), if desired, it is easy to select an electric outboard motor that will fully satisfy the requirements for the minimum permissible motor power. On the other hand, with equal power, different maximum thrust is possible – for example, 2.5 hp motors of different brands with 35 kg and 36 kg traction. Even if we proceed from the nominal maximum power, for example, gasoline engines of different brands for 2.3 hp and 2.6 hp give an equal tractive force of 28 kg. There is no direct dependence on horsepower. ![]() In reality, the traction force of any outboard motor depends on several factors, from the design features of the outboard motor to the weight of the boat and cargo and the propeller’s design. Secondly, even if we ignore some errors of “conversion” and proceed from the lowest required power, the number of obtained horsepower is quite enough for trouble-free sailing in an inflatable boat. But! First, the conversion of thrust to horsepower (and vice versa) is not entirely correct. ![]() And this equivalent greatly confuses the potential user: the minimum is about 0.2 hp, and the average is 0.5-0.65 hp. However, many sellers and even manufacturers of electric motors convert pounds to kilograms for the convenience of buyers and show the equivalent of horsepower next to the traction force. Often, the traction force of boat electric motors is also indicated in Newtons. Moreover, both units of measurement are already considered obsolete, and in the International System of Units (SI), force is measured in Newtons (N, N). Although, strictly speaking, pulling force is measured in kilogram-force or pound-force units. It is generally expressed in kilograms or pounds (lb). Traction force (thrust) usually indicates a characteristic of the power of electric motors. Getting acquainted with electric motors, you will notice that the power is mentioned not in horsepowers or kilowatts, which is usual for gasoline motors. Nevertheless, everything in the world is relative. Usually, the disadvantages of an electric outboard motor are considered low power (which is associated with low speed) and low autonomy (the time and mileage of swimming depending on the battery’s capacity and the mode of operation). Disadvantages of an electric outboard motor Moreover, electric boat motors can fit a rowing inflatable boat with a hinged transom and a compact motorboat with a stationary transom. ![]() you do not expect to perform planning) – perhaps you will consider the electric motor the best option. But if the inflatable boat is designed for a low-power engine and is used in displacement mode (i.e. If your inflatable motorboat was designed for a relatively powerful outboard motor and you like planning at a reasonably high speed, there are no suitable electric boat motors. Today, an electric boat outboard motor is a pretty worthy alternative to internal combustion engines in many cases. We do not give preference to any outboards manufacturer for objectivity, and we do not mention the names.Įxcept for the hand-powered outboard propeller driven by American Thomas Rees, the first genuine electric outboard motor was introduced by the Frenchman Gustave Trouve in 1881. The result is information that will help you choose an outboard motor for an inflatable boat more objectively. ![]() We also “sifted” the opinions spread on the Internet and the press. We considered the manufacturers of outboard motors, honest assessments of experts and boaters, and our boating experience in testing motors of various types and brands. Electric outboard VS Petrol outboard motorīoat electric motors are not inferior to petrol motors because of the number of stereotypes associated with their advantages and disadvantages.
