You can see it in action in all of its next-to-silent glory in the second video. Basically, though, he constructed an adaptor for the new motor to fit the existing shaft, threw in some used Tesla batteries that had previously been in Mercedes Smart Car EVs…and had himself an electric I/O.Īn electric I/O that goes almost 60 km/h (35 knots/40 mph). They are carefully detailed in the video and pointed out as Scott does a tour of the install. You can see in the video below the things that needed to be done to fully switch things over. Scott set to work re-rigging the Bayliner. So he purchased a brand new 17.5 foot Bayliner, ripped out the brand new Mercruiser 3.0 litre motor and replaced it with a high torque motor from the HPEV company that is designed for use in mining vehicles: the AC-34 X 2, a 100 kW/147 hp permanent magnet 3 phase AC induction oil cooled motor. Speed, however, has its own pleasures, and Scott decided to see what could happen with more power. (And worrying what might conk out next.) Enough pontoon boat. In fact, he found that cruising around at the leisurely pace of a pontoon boat was even more pleasurable without the sound and fumes of a gas burner. He hasn’t had a problem with the boat since. He went and bought what he describes as ‘a golf cart motor on steroids’ and converted the outboard to electric. Scott is an inveterate tinkerer, so he got to the idea of converting the pontoon to electric drive. Well, as with many used boats, there were numerous unexpected problems and Scott, not surprisingly, got fed up dealing with them. Scott wasn’t even a boater, but they live near a lake and it seemed like a pleasant way to spend time together, out on the water. Where he started was with Scott’s wife suggesting that they buy an old pontoon boat. However, some engines do perform better than others in terms of fuel efficiency with inboard diesels usually offering the best fuel efficiency, followed by. Scott didn’t start with the Stealth – that is where he has ended up. ![]() Here’s a video giving you a full tour of how it looks when it’s completed and ready for shipping. Stealth was launched last year and Scott is fielding orders for the Stealth 40 from as far away as Sweden. ![]() The controls are even the same, aside from a few concealed modifications Scott incorporates. He puts in an electric motor using mounts and other customizations he has developed over the past couple of years through lots of experimentation.įor all intents and purposes it looks like a gas outboard. Scott actually orders Yamaha 40 HP motors from an OEM with everything except the powerhead. He is the owner of Stealth Electric Outboards, which makes electric motors equivalent to a Yamaha 40. But before we get to the I/O conversion, a little bit about Scott. That’s why we like this one by Scott Masterson of Houston. There are are fair number of YouTube videos and other instructionals that cover the idea of converting a fossil fuel outboard to an electric, but not many that detail converting a standard inboard/outboard setup to electric powered.
