Electric Boat Motors

Electric boat motors are now being installed in some newer models of boats. Electric boat motors make a quieter, cleaner ride possible because they aren't burning gasoline and damaging the environment.  

They also cost less to maintain, only requiring that the battery be charged.  Also, many people use boats for fishing, either for business or pleasure.  They often find that fish are easily scared away by the loud sounds of a conventional boat engine, so they end up having to drift further away to another spot.  These are reasons to purchase an electric boat motor.  There are very few if any fuel costs.  An electric boat motor is also safe; it won’t leak fuel into the water, as some gasoline motors have been known to do.  You should look into having an electric motor installed, or trade your boat in toward an electric model; the benefits will offset the cost.

How Electric Boat Motors Work

Electric boat motors run on a battery, which is connected to the gears and the motor assembly; they use an electromagnetic force to turn the motor and thereby the propeller.  Sometimes, the motor doesn’t use a gear assembly at all.  This is to be expected because no matter how smoothly they turn, gears will lose energy when they transfer force to the next gear in the assembly.  This results in lower power output and the need to use more power to achieve the same speed.  When a battery needs to be charged, it can either be plugged into a power supply at the shore, or there are other ways of gathering power for the electric boat motor while on the water.  The most common method of doing this is to use solar panels.  However, when using solar panels, they have to be aimed directly at the sun, or they don’t gather as much energy as they would otherwise.  Towing generators is another method, but it takes more power for the electric boat motor to tow them along even though the water would hold up most of their weight.

Advantages Of An Electric Boat Motor

An electric boat motor is quieter.  The sound of gears turning, as well as the internal combustion engine of standard boats, tends to make a lot of excess noise.  They don’t require the use of a lot of gasoline, if any, so the issue of pollution is practically non existent.  Because of this, fueling an electric motor only requires a power outlet to plug the battery into for charging, so it doesn’t cost money for gasoline.  Some models use a small combustion engine’s alternator to provide the electric charge for the main motor, but even in these cases, cost is far reduced.

Common Fear Of Electric Boat Motors

One reason people have for not initially wanting to switch to an electric boat motor is the fear that they will be at risk of electric shock because water conducts electricity.  If the actual source of the electrical current is unshielded and ungrounded, this is indeed the case.  Also, only a certain amount of electrical current will pass through water – materials don’t have infinite conductivity.  As long as the motor and the main part of the boat are properly insulated from electrical current, there is no danger.

What To Know About Electric Boat Motors

To use a fast electric boat motor properly, a speed lever has to be included.  This lever simply controls the direction of the engine’s rotation, as in whether it’s going forward, slowing down, or going in reverse.  It operates in conjunction with the rudder to move and steer the boat.  Fast electric boat motors operate by using the charge of electricity to run the propeller.  The battery requires charging at set intervals, depending on the model and how often it’s used, as well as the age of the battery.

Boat batteries have NiMH battery packs, each with a set charge time.  NiMH is a nickel-magnesium alloy with hydrogen infused.  It holds the most electricity, and can hold a 2.5 amp-hour charge.  Depending on the type of alloy used, battery packs will have different charge efficiency based on factors such as heat.

What To Look For In An Electric Boat Motor

Electric boat motors can be bought at many different shops, and there are plenty of brands available.  You can find some good information on these at www.nauticexpo.com.  It’s best to get a brand that’s well known because they’ll have the best warranty if it turns out to be needed.  Honda™, Yamaha™, and Mercury™ are the three best.  Each of these brands has different features.  Some motors have things like cable steering and hydraulic tilt.  These features will decrease the amount of power the boat motor uses, and increase its available running time without having to recharge.  It should also be easy to wire these to solar panels or a rechargeable generator.  Usually, rechargeable generators are towed along, but if you decide to buy one of these, be sure your motor will output enough wattage to compensate.  Most of the time, electric boat motors can be plugged into an outlet shore side.  Solar power is becoming an increasingly popular option though.

Using an electric boat motor is a good way to save on fuel costs and to positively affect the environment.  Also, fuel cells are easily recyclable once the batteries have reached the point at which they can no longer be recharged.  You’ll still get plenty of use from a single battery pack, because it can be recharged multiple times before losing its conductivity.  Electric boat motors typically cost $100 to $200.  Electric boat motors can easily be connected to an existing engine for the smoothest and quietest boat ride you’ll ever have.
