This is the first test video of the E-Doo Electric Seadoo Boat Conversion Project where the owner converts a 2002 Seadoo Utopia 185 with a broken motor into an electric battery powered boat!
In this video we take the boat out testing with 6.5 people onboard and a big dog (so probably the weight of 7 people total). I manage to wake surf on this trip. The wake is not the best for surfing and it needs about another mile per hour or so to get surf without the rope but it did tow me! Bad news though, the boat refuses to plane. Looking at the motor specs it would seem this will be helped by adding the extra battery bank I have been talking about and bending the impeller - tune into the end of the video to see more explanation and the footage of what happened! Also we towed it using our new Tesla Model Y (electric vehicle towing EV boat about 50 miles) and that worked out great! Even pulled it just fine as the tire fell off and I had to drag the wheel-less trailer to get off the road with the Tesla (see video for details).
