Evoy Developing 150 hp Electric Outboard Motor With Hurtigruten & Frydenbø - CleanTechnica

Evoy, based in Florø, Norway, is working on keeping the pristine seascape protected. It has developed a 100% electric propulsion system for high-speed boats. Presently, the company is preparing to expand its portfolio to a turnkey 150 hp outboard system with batteries.

If it’s reliable I don’t care if it runs on rams piss

Well Ram's piss would keep the Pristine seascape protected for sure. 😊

A bit light on the operational statistics.

What battery weight and range we talking about?

That was my first thought. If this goes on an 18 foot boat, which can handle it, adding over 200 pounds of batteries
could be a problem to store in the boat.

150 HP is a lot of power for a 18 foot boat. Sounds more like something for 20 - 22 ft. (Been a long time since I owned an outboard however). Gasoline weighs 6.75 pounds per gallon. 200 pounds is 30 gallons. I am going to guess that 30 gallons can run that size outboard for about 5 to 6 hours.

If someone has better numbers for power and fuel consumption, please correct me.

I have a 90 2 stroke on my just under 18' Sea Pro DC180. While I could have probably gone to a 115 in 99 when I bought it, I would lose fillings trying to run it home full speed in a Great South Bay afternoon chop with a 115. (Now with 18 implants I wouldn't be losing fillings and could have gotten home faster, but since 2004 when I started kayaking...) Seriously, if the batteries on an 18' would approach 200 lbs, I would lose 3 or 4 knots and take forever to get up on plane.

I would think the voltage rating will play a big part, I don't see this running on 12v, 24v to 32v would be my guess.
The weight of the batteries will play a big factor as that weight will not change more that .05 percent.
The concept is good, recharging with solar panels i'm sure will be offered, battery technology is going to have to get a lot better, as far as weight and holding a charge goes, I can see a hybrid , with a small generator as main and batts as backup, but that defeats the purpose of a fuel free, emissions free engine.

Hybrid cars are efficient because they use dynamic breaking which puts the energy of the car's motion back into the batteries rather than dissipating it as heat in a friction brake. Boats don't brake that way so the hybrid concept could not apply.

Electric would be great for launches bringing people out to boats that or moored. No stinky smoke, less noise and no oily bilge water going over the side.

Hybrid still fits, if it runs on gas and electricity it's considered a hybrid.
