Electric boat motors


What kind of motors were in the Soviet Union

With electric outboard motor I first became personally acquainted in childhood, in the 80s. Soviet industry such motors were not allowed, and my father made his drawing of the famous book “100 jobs for skilled hands.” Motor design was brilliant in its simplicity: a 12-volt DC motor inside cans-housing, spun brass propeller mounted on a shaft of the motor. The steering column was made from water pipe and a bent letter “G” and attached the motor to the transom of a boat by means of ordinary carpenter’s clamps. Worked motor from a car battery, on-off toggle switch, speed control and reverse were not, and if you really needed back up, had to swap the terminals on the battery.

The design looked pretty ridiculous, but still for the time it was a real technological breakthrough! Easy and convenient electric motor had a lot of advantages over manufactured then a two-stroke petrol engines with a capacity of 2 horsepower: “salute-2” (“Sputnik”) and “Breeze-2”. “Salute” in the environment of vodnomotornikov were called “Designer “DIY”, and “Breeze” as “materkom” and do not call.

The motor was incredibly simple and reliable in operation and, despite a capacity of just 0.35 kW, confidently pushed on the lake inflatable “VEGA” with a wooden transom. I’m not talking about the fact that the engine worked almost silently, allowed to drag along the lake path, and also to keep the boat in one place. The main drawback of the motor leaks a homemade cover and a car battery, which is very quickly discharged and began to crumble under heavy loads and high humidity.

Modern electric motors

Today on sale there are dozens of modern ergonomic models of outboard motors and batteries to them which devoid of these shortcomings and allow us to meet the needs of almost any angler. But in General, the principle of simplicity and the reliability of the design remains unchanged over the years.

Very often we hear the question: “which boat motor is better – gasoline or electric?”

This question is not quite correct, and unambiguous answer cannot be. It’s like comparing petrol and electric. Each has its advantages and disadvantages, and ideally, it’s probably best to have both. Same thing with boat motors. For large rivers with strong current and travel great distances at high speeds the electric motor is suitable small, or not suitable at all, but for lakes, reservoirs and rivers with low flow, it is suitable as it is impossible by the way. The electric motor allows silent and (most importantly!) without any harm the ecosystem of the pond to get to the most inaccessible places, including in bushes in shallow water. The electric motor is simply irreplaceable for trolling and slow of movement and maneuvering on the water when fishing, spinning, circles, vertical and jig conventional fishing rod. The advantages of electric motors over petrol is the same almost complete absence of operating costs. The electric motor requires no maintenance and conservation for winter storage.

Before proceeding to the choice of electric boat motor, you should familiarize yourself with their basic characteristics, which differ somewhat from the usual characteristics of gasoline engines.

First and foremost, you need to pay attention to the traction motor, which is measured in pounds (lbc) or kilograms. One pound is equal to 0,453 kg. pulling force is chosen depending on the loaded mass of the boat. Often on the market there are engines with a thrust of 12 to 40 kg. for Example, for boats with full weight 600 kg engine with enough towing capacity of 13.6 kg (30 lbc). For heavy boats, with a curb weight of 1200 kg, you will need a motor with a thrust of 36 kg (80 lbc). Optimally suited to the specific boat model traction motor power is calculated according to special tables.

Working voltage of motor – most 12, however, there are models for 24 V consumed by the motor current is measured in amperes. Maximum quiescent current is the current at full load. Its value in various models – from 30 to 60 amps. In accordance with the maximum current consumption is selected and battery.

The power of the motor, as well as fuel motors, measured in kilowatts (kW) and horsepower (HP, hp). 1 horsepower equals 0,736 kW.

Adjust the speed of the motors is smooth (CVT), and is fixed. Such motors usually have from 3 to 5 speeds forward and 1 to 3 ago. The length of the deadwood (or “legs”) are selected in accordance with the size of the boat.

The mass of the motor depends on its power and maximum traction. Usually it is from 3 to 15 kg.

Motor control is performed most often using the tiller, but there are models with foot pedal or remote control. The pedal provides a number of advantages, for example, when trolling, unloading with both hands.

Separately want to say about batteries. Many anglers for reasons of economy, use a regular car battery. Make it impractical, since starter batteries are, by definition, is not intended for use as a traction battery. And it is absolutely unacceptable to use the same battery for the boat and for the car. In this case, you are most likely simply not able to start your car after fishing.

Manufacturers of engines today offer a rich selection of gel batteries high capacity, which are specially designed for specific operating conditions on the water, working up to 18-20 hours straight without recharging and have a special design that provides the maximum number of cycles “charge-deep discharge”. By the way, many modern motors have built-in charge indicator that allows you to control the degree of discharge.

For a more complete and detailed information on the features of the different models we offer log in category outboard motors in the online store Filandia.ru, where a wide assortment of not only motors, but also a variety of accessories – from traction batteries and chargers to the power tiller and control.
