In the right situation an electric outboard motor can be absolutely magical. If you are a pleasure boater, or an angler on a lake or a canal or similar, what could be nicer or more rewarding than the silent running and zero pollution that an electric outboard motor provides? batteries for a fishing boat
Electrical outboards can move surprising heavy weights, but as always, sense has to prevail. My own boat, is thirty feet long and weighs around five tons. We have lived on board since 2001, and because we are moored in non-tidal waters we could, if we chose to, move from A to B with an electric outboard motor. The water where our boat is moored connects to several tidal rivers and the sea. Tidal and sea do not make good bed fellows with small electric outboards, except in a marina or sheltered inlets!
Not so much now, but when I was younger, there was nothing that I enjoyed more than fishing for Trout. Here where I live, most of the available Trout fishing is reservoir based and you can either fish from the bank, or hire a boat and row around the reservoir. Reservoirs can be huge, and covering an area can be exhausting if all you have is a pair of oars. The alternative was to take an electric outboard and battery. When I fished with my older cousin, John, he always took his electric outboard motor. If the fishing was not good, we would move about 100 yards, and give the fish a go there. The simple pleasure of moving, during a full day, from spot to spot without backache was completely showing off I suppose, but having used the previous comma to have a think, I don’t believe that we ever got back to the reservoir office without our full allowance of fish. Just to clarify that last statement, where I live the reservoirs, while containing some native Brown Trout, are mostly stocked with foreign Rainbow Trout. These fish seem not to be able to breed in our waters sadly. Thing is that stocking a reservoir with Trout costs money, and, here at least, you will be prevented from taking more than the allowed quota, possibly only two fish depending on the ticket you buy.
But this article is not about fishing, it is about electric outboard motors. All you need is a boat ( obviously ), an electric outboard motor and a decent battery. The battery is very important. If you were to use a standard starter battery, it would fail very quickly. Starter batteries are designed for a huge burst of amperage, to spin a car engine, and then receive an instant top up from the engine’s alternator. These batteries, though acceptable in an emergency, are generally useless for ongoing leisure use. You need a ‘proper’ leisure battery. Not one that is being sold as leisure / starter. A leisure battery, a real one, is capable of a high rate of discharge, maybe 40 to 50%. Recharging will not affect the batteries life significantly. This is the real difference. Proper ‘leisure’ batteries are perfectly capable of deep discharge, and will recover. Starter batteries do not like, and are not capable, of deep discharge on a regular basis. The most common reason for this is that starter batteries have much thinner internal plates.
One thing that you should also consider is theft. Electric outboard motors are extremely light. Therefore there is no excuse to leave one on your boat! If it is not there it is not going to be stolen.
