Re: [Electric Boats] Outboard to Inboard

 

When you remove the top you will see that it is just a hollow shaft. All you are doing is shortening that shaft, sticking it through the hull and remounting the head. If you use a G10 tube for the whole thing to go through it will just rotate on the tube. As long as the tube is above the water line no water will enter the cockpit.

Thanks Dan.

It looks like the electricboats site in the UK was referencing Sillette saildrives. It also appears that they have units that range from 2.8kW (direct drive) to 4.8 to 8kW (2:1 reduction) depending on the motor chosen by the installer. I think that electric saildrives are simpler than ICE versions because electric motors eliminate the vibration concerns related to mounting engines like that.

An electric pod mounted permanently under the waterline would be theoretically more efficient, but protecting the motor from water intrusion 24 hours a day can be problematic. I think that the Re-E-power pods suffered from problems with their seals.

Does anyone here know if Sillette has a US distributor? It seems like an effective solution for some conversions.

Fair winds,
Eric

PS: Due to the cost of Torqeedo products, I would be hesitant to take mine apart for components in a DIY engineering experiment. But maybe that's just me... ;)

All you would need is a 1" hole in the bottom to attach the unit. Plus if you made some kind of attachment you could still turn the motor head for direction (Just a small knob).
