Electric motors are great , efficient, powerful , high torque starting from zero RPM
are a different issue. You'll be as comfortable with electric as using a gas or diesel engine with only a half gallon of fuel in the tank.
That was the generalities. Now to the specifics of ePropulsion, which I recently looked into.
The pods are scary for boats that have to live in the water . For a trailerable boat the ePropulsion pod may be ok. A Volvo
or Yanmar saildrive
that has a minor leak may still run to some extent . A minor leak inside an electric drive is an instant disaster.
Epropulsion does not offer spare parts for sale
are to be handled by your dealer. You haul out
the boat, remove the problem part, send it to your dealer who sends it to ePropulsion for repair
. These dealers are not prepared to handle electrical
so no matter how small of an issue you have, it will travel thru your dealer to Epropulsion and then returned to you if still under warranty.
are heavily involved , the motor, controls , battery and charger
communicate thru a proprietary ePropulsion method. If something goes wrong with one of these components there's no easy way to diagnose the system.
That's very different from having a diesel transmission
It is not clear whether the battery may be used as a plain battery, with a third party load. The motor and battery are communicating together. A lot of features are based on the system components communication. A lot of functionality is based on the system making decisions for you. For example if the battery or motor exceeds a certain temperature then it reduces throttle automatically, even if you were pushing it hard to avoid a collision
In my opinion there are too many interdependencies and proprietary elements in the ePropulsion system .
If you want to use the pod and controls with a third party battery, again some features won't work .
Bottom line, I love the idea of electric despite the still abysmal range limitaitons. I absolutely do not want a proprietary closed system where I am locked into buying
an ePropulsion battery . It'd be like having to buy a Volvo fuel tank
to use with their diesel and when it fails , remove from boat and send to Volvo thru dealer.
