ELECTRIC OUTBOARD MOTORS were originally conceived, designed and built for trolling. "Trollig motor" is their English name / designation that defines their purpose. So there is no need to dream of high-speed movements under them for long distances. But boat motors are famous for:
the ability to overcome shallow water areas even 30-50 centimeters deep (with a gas engine there only on oars)
non-hook propellers, which hardly wrap around grass and algae
very light weight and easy installation on any watercraft (you will never have a question: how to put an electric motor on a boat?)
the absence of any special requirements for their long-term storage (they winter well in ordinary city apartments, without giving out their presence with the "aromas" of gasoline)
well, and, of course, 100% environmental friendliness compared to gasoline counterparts (in civilized countries in many reservoirs, driving on gasoline engines is prohibited)
Having made the final decision to buy an electric motor, you need to try to determine as precisely as possible: which electric motor for a boat is better suited specifically for my fishing conditions? It is very easy to calculate the approximate power (tractive effort) of boat electric motors, which, according to their technical parameters, will ideally fit on the transom of your boat. Plus: the weight of the boat, the weight of the passengers, the weight of the cargo / equipment on board. If you are also going to hunt on a boat with an electric motor, add the weight of the hunting dog to the general "weight pot". Let's say you have a total of 400 kilograms. We add another 100 kg to have a safety margin. It turns out that you need to buy yourself an electric motor capable of "pushing" a boat weighing 500 kilograms, with a pulling power / force of at least 14 kg (in English pounds: 30 Lb). Almost any electric motor can do this, and 30 lbs, and 40 lbs, and 55 lbs.
Usually, all these parameters / indicators are indicated in technical specifications, technical data sheets, and in annotations / descriptions for each specific model of the outboard electric motor.
But be sure to take into account (!): That these averaged calculated indicators are indicated for reservoirs without a flow with stagnant water.
When planning to move along the river, it is worthwhile to select the electric motor in advance by proportionally increasing its tractive power, so that, if necessary, it would be possible to move the boat without any problems even against the current.
How to match the battery to the boat's electric motor? And can a regular car battery be used? These two questions are often asked to the managers of our online store Optimys.com.ua.
Let's try to briefly answer them. Car / starter batteries are rated for a one-time maximum load to quickly start a car's engine. They do not like long-term work with constant loads, with the same voltage. They are contraindicated to discharge more than 50-60 percent of the total capacity, not to mention a deeper discharge. In principle, car / starter batteries can be used with outboard electric boat motors. But it is possible that by doing this you will very soon render your car / starter battery unusable. Therefore, so-called "traction batteries" have been specially developed for outboard electric boat motors.
