I’ve got a Falcon (boat) that I have considered doing an Electric motor transplant. It’s a Thunderbird Falcon with a stern drive and 5.7L
Mercruiser. Tank and engine weigh about 300kg. Battery(70kWHr) and 260hp electric motor weigh 600kg. Boat carries 10, but I don’t have that many friends. Take away 4 x 75kg(300kg) people, gives me an electric boat capable of carrying 6 people.
Many emails to German company supplying Motor and battery pack, but wouldn’t give me a price. So I’m guessing $30-40k. It will probably cost me $1000 each time I go out on the water, over 3-4 years.
After a couple hours of skiing, I’ll need to connect it up to a 30kVA generator, to recharge.
Ahhh, the serenity... Until the salt water gets into the battery pack.. Then BOOM.
Silent boating and no fumes as you get into boat after a ski, would be good though.
My concern is that the batteries will be old tech in 5 years. The same weight with next generation batteries could get me more than 2 hours. Plus not as explosive when mixed with water.
