Boat Electric Engine

This would be for sea use

yes, the torqeedo cruise electric outboard has the power of up to a 6hp outboard motor. it is a 24v electric motor and is capable of moving a 16' open boat at displacement speed. the range will depend on the size, number and type of deep cycle batteries that it is hooked up to. they are designed to work in fresh or salt water.

they also make a cruise r model (9.9hp) 48v

This is the first test of a prototype electric outboard motor built by Inertia Labs under commission (www.inertia-labs.com ). The goal was to get ...

I am building a two-seater, electric catamaran, 21 ft. long, about 8 knots top speed, no sails, just two electric DC engines. I am aiming at a range of about 20 miles before it needs recharging, and my only recharging device will be a wind turbine. I've seen they do about 100 - 400 Watts when they are the marine type which usually attaches to sailboats; how long would it take for such a turbine to replenish energy in my boat, would anyone know? I'm hopeless with these things, but I still love doing them.
Thanks so much!

If you shoot for a very efficient design, it might work OK. I wouldn't plan on carrying the turbine with me on the boat. If you could leave it somewhere & hook-up to it when you get there, it would be more practical.

8 knots isn't too fast. 20 miles at 8 knots is about 2 hours transit time. Two 1/2 HP motors would work. Human powered catamarans have gone much faster than 8 knots & one man is about 1/2 HP or 375 Watts.

If the motors and propellers are efficient, then a total of 600 Watts might do it, assuming two passengers.

Let's say the turbine generates 200 Watts. Then you'd have to recharge for about 6 hours.

I've assumed 100% efficiency throughout. The true efficiencies are pretty high with good equipment, but not 100%; so figure 7 or 8 hours of recharging.

So I have an old Evinrude 80 outboard engine and I can't get it to run. I checked the fuel delivery and it seems to function, and the plugs are less than perfect, but they work.

the electric starter runs turns the engine over and then the engine stops. I can't get it to run for more than a second. We tried starting it with some starter fluid and it ran with a continuous spray of starter fluid. When the other person stopped spraying it the engine would run for 3 seconds tops and then it would just stop.

What could be the problem?

It's deffinately a fuel problem. First remove the gas line from the fuel pump. Thats the thing with a black plastic cover with a screw in the middle. Then pump your primer ball and make sure gas is going thru the gas line. Next, hold your thumb over the gas line and pump the primer ball and look for leaks anywhere in that line. Next replace the main gas line and do the same with the line going to the main carb. Next replace that gas line and pull the plugs from the carb bowls and pump the primer ball. Check the condition of the gas that comes out. If it is at all funky, rebuild the carbs. Oh and make sure you are using new clean gas with the right oil mixture.

Is their an electric motor that could replace a 6 hp 2 stroke engine for a little tinny or are electric motors only suitable for moving short distances (so i if i had the electric motor i would still need the petrol one anyway?)
An electric motor would be good because they are cleaner and scare the fish less.
So electric motors don't have a very big range?

if you don't mind going v-e-r-y slow, then leave the 6hp at home.

otherwise, trolling motors are there to replace the oars or paddles. I use mine mostly for repositioning while fishing.

Thing is, gasoline is just a much much more effecient way to store energy than is lead and acid. The battery bank to power an electric motor that performs anywhere near your 6hp would be prohibitively heavy.

For a small boat you'd want a 12-volt motor (to avoid the weight of the 2nd battery). MInnKota and Motorguide both spec their 12-volt motors at 40 amps, but they don't draw nearly that unless the boat's really heavy and you're pushing though thick hydrilla or something. Figure around 20-25 amps on average.

With a 90 amp-hour battery, that gets you neighborhood of 3 hours run time until the battery is drained to a 20% state of charge; but if you're running it continuously (vs on & off) you'll drain the battery faster.

A 12-volt 50-lb thrust electric motor will push a small aluminum boat maybe 5 mph.

You'll want the biggest, heaviest marine deepcycle battery you can afford. I use Walmart's group 27 trolling battery

Wanted a nice little boat around 14 FT. It must hold 3 people. I also heard some of the jon boats have electric engines.

They type of boat will vary depending on the type of water you are planning to be on. For calmer flatter water a jon boat works great and most 14 foot jon's can take a Goos sized outbord along with an electric motor. Now if the water will be rougher you will want a V hull or semi V. This will cut through the waves and not slap against them so much. As with the jon boat this will work well in flat water and will not blow around in the wind as much because of the hull design. Below will be some links to some reputable boat companies so you can compare the utility and costs.
