Electric Motors: A basic guide

AN electric powered motor is one of the maximum trolling motor features useful accessories that can be established on a sportfishing boat. MICK FLETORIDIS explains why you need to have one.
THE electric trolling motor has evolved to grow to be one of the most essential add-ons anglers can deploy on their boats. While an electric mightn’t immediately capture you greater fish, it’ll put you of their location more stealthily, and within the case of many contemporary models, maintain you immediate using modern GPS era. Many electric powered cars may also mechanically steer a route along a troll line, run simply silently, set up at the frenzy of a button and extra. If best they may brew coffee!
Electric evolution
Like many keen anglers, I’ve lengthy trusted electric powered trolling vehicles to assist my fishing. The first electric powered motor I owned become a Shakespeare 12v 24lb thrust model bought within the ‘80s to be used on a canoe and a 10ft Brooker tinny. While now not as sophisticated because the modern-day crop of electrics, that antique Shakespeare repaid its preliminary outlay value ($seventy five from memory) many times over the years, broadly speaking trolling for trout in the Snowy Mountains and natives in south western NSW. Being a fundamental design although, the Shakespeare’s three-pace toggle transfer set on High could drain a completely charged automobile battery (pre deep cycle battery availability) in quick time.

When I upgraded to a three.9m Stessl Edge Tracker I outfitted a Minn-Kota 42lb bow-mount 12v electric with foot pedal control and autopilot – on the time these cars weren’t common region in Australia. It become also a freshwater version, the precursor to the later Riptide saltwater series. That motor introduced years of problem loose obligation and helped me fish for the whole lot from trout to natives, flatties and bream. When upgrading once more to a four.3m Webster Bassmaster, I mounted a new Riptide 12v 42lb thrust Minn-Kota bow-mount, later retrofitted with a Co-Pilot far off manage. That motor changed into used on the general public of my fishing journeys over the subsequent 10 years, other than offshore, and indirectly caught me a lot of fish.

A Jarvis Walker Watersnake 55lb thrust bow-mount electric powered resides at the cutting-edge boat in my shed – a three.9m Quintrex Hornet Trophy. The point of all this is that any fishing boat I very own should have an electric powered motor geared up. For mine, an electric motor is as crucial as a sounder/GPS unit for purchasing linked to fish. So in case you’ve in no way owned an electric powered motor, here’s what you want to understand.

History of electrics
The first electric powered trolling motor was invented through O.G. Schmidt in 1934 in Minnesota, North Dakota, USA. The motor was a simple layout achieved by attaching a starter motor from a Ford Model A car to a bendy shaft and propeller. Schmidt’s invention later resulted within the start of the Minn Kota Manufacturing Company, named after its area close to the Minnesota/North Dakota border. As well as Minn Kota, there are different professional manufacturers of electrical trolling automobiles at the Australian marketplace nowadays which includes Motorguide and Watersnake. All offer propulsion thru brushed electric automobiles pushed by way of 12 or 24v DC battery power.

Unlike petrol outboards which might be rated in horsepower, electrics are rated by way of their propulsion force at full pace, measured in pounds thrust. As a preferred guide, 12v creates thrust up to 60lb with currents as much as 55 amps, 24v will create thrust to 100lb and modern to 55 amps. To offer the power, 12v marine deep cycle sealed lead acid batteries are maximum normally used. Unlike vehicle batteries, deep cycle batteries are designed to resist regular discharging without harm. The present day electric powered is designed around a motor sealed interior a watertight compartment at the quit of the force shaft. Being submerged in the course of operation, prevents the motor overheating.

Which motor?
Typically, on a ship outfitted with an electric motor the gasoline-pushed engine is used to quick get from area to region, even as the electrical is only used whilst fishing. An electric powered motor performs fine for gradual velocity manoeuvring while trap or fly fishing, trolling or to help preserve function in present day or towards wind. In case of a main engine breakdown an electric powered may also get you domestic in beneficial situations, however is pleasant not relied on for that reason.

The electric powered motor that first-rate suits your boat comes down to boat size, weight and supposed purpose. Selecting the precise motor may be tough as there are numerous variables, and electric powered motor manufacturers normally best provide basic recommendations. As a simple manual, every 100lb (45kg) of boat weight requires around 2lb of thrust. Going by that, in case you’ve were given a famous sized boat of around four.5m that weighs 1000kg (which includes, motor, gas and a pair of x occupants) that’s around 2200lb, which equates to 44lb of thrust.

Given that maximum fishos cart way greater tools on boats than they need a little leeway is required, but in this example a common 12-volt electric version offering 55lb of thrust ought to thoroughly do the task. As whilst selecting the strength score of your fuel engine, it’s additionally high-quality to keep away from over or beneath powering your boat with an electric motor.

Bow or stern mount?
This is a large consideration when choosing an electric. In standard phrases, bow mounts pull the boat thru the water and steer quicker, the usage of less strength than a stern set up motor that pushes the hull. Bow mounts can also normally be operated remotely that’s a large gain when fishing. Bow mount electrics are commonly deployed via depressing a lever by foot even as simultaneously sliding the motor housing from its cradle by means of hand. In the case of the lately launched Minn Kota Ulterra, deployment may be completed through a hint of a button on the unit’s i-pilot faraway control. If there’s a disadvantage of state-of-the-art bow mounts like this it’s generally handiest the preliminary outlay.

If you ought to in the main troll under electric powered energy a tiller manage version established at the boat’s transom may fit you high-quality. There are lots of tiller control fashions on the market and most are reasonably priced, particularly in assessment to better specced bow-mount electrics. Most tiller manage fashions feature a twist throttle like a petrol outboard, and a simple locking tilt/trim arrangement. Tiller control models are typically 12v powered and offer as much as 55lb thrust, with some manufacturers supplying higher propulsion models. An advantage of the tiller manipulate electrics is they can be easily adapted for use on canoes and kayaks.

Bow mount electrics as their title suggests are suited for the boat’s pointy end, typically thru a shape of brief launch plate that permits for clean elimination for journey, upkeep or safety. Operating bow mount electrics is generally executed thru a foot control or wireless remote. Most foot controls have on/off, velocity and guidance controls with the latter operating through electronically managed servo motors. Many bow mounts come ready with both foot and wi-fi remote manage because of this operators can choose which system suits them nice. In current years, key-fob style far flung transmitters have revolutionised electric powered motor controls. These remotes – which are generally worn via a lanyard across the neck or as a wristwatch style – no longer handiest steer and direct the boat, they could maintain your position even in cutting-edge and wind using GPS generation. Trollers also are able to point their boat in the course they want to run and the motor will self modify to preserve the boat on route.

While motor depth is adjustable it’s important to pick out the proper shaft period on your boat to keep away from capacity cavitation troubles.
While motor intensity is adjustable it’s vital to choose the proper shaft length on your boat to avoid capability cavitation problems.
Height gain
Electric motors are to be had with one-of-a-kind shaft lengths, so when deciding on one on your boat it’s vital to get it right. While the intensity of the motor is generally adjustable through a popular locking collar machine, having enough length for adjustment first of all will prevent issues. If your boat has a healthful quantity of freeboard the motor can be set up a longer distance above the water floor and require an extended shaft than a decrease slung craft. When fishing in any swell the rise and fall of the boat will see the electric motor housing do the same. This is accentuated in the case of a bow installed electric powered. If the motor shaft is simply too quick the motor propeller will cavitate at the surface on maximum rise and make steerage and manoeuvring the boat very difficult. If you’re uncertain which length fits your boat ask the provider or someone who has the identical boat as you. Online boards can be a outstanding source of info for this form of issue. As a general rule, in this case, longer is commonly higher.

12 or 24 volt?
Having by no means owned or operated a 24v electric motor I can’t see a big need for one, but, when you have a huge heavier boat that might warfare from the most thrust offered by a 12v model going to 24v is possibly your exceptional bet. The primary attention with going up in voltage is the greater weight and bulk of installing more batteries and the associated cabling. If you’ve got a mean weight boat of up to 5m, that is the sort of craft extra usually fitted with electric automobiles, a 12v model need to be available to fit your needs. Considering different elements together with hull form, windage and more will affect this choice. The exceptional way to slim down your preference of electrical motor is to talk to owners of similar boats to yours who can give you firsthand advice on any potential pitfalls. Once you’ve chosen the right electric motor on your boat you’ll be amazed at how a good deal your fishing will advantage. Ultimately, you’ll be catching extra fish.
