Re: Electric Power a sobering story

Part of the cover looks fine. The stainless hardware looks fine. Even the cover with their sticker on it looks ok. The rest looks like it went underwater. Everything else in that area looks normal too. If it was manufactured properly it would all look about the same. I put most of this on the manufacturer.

There's a guy on the Chesapeake who posts in another forum who has had a 3kw ePropulsion pod drive on his H-boat for several years. He is happy with it but has few good things to say about ePropulsion customer service. His installed cost came to about $6k including a modest battery plant.

On that I agree. If Oceanvolt simply sold him the parts and he installed them poorly ok that is on the owner/installer but he paid for certification which is obviously not worth the paper it is written on.

Re: Electric Power a sobering story

I'm a bit suspicious of what has happened to this motor, but in general how should electric propulsion systems be expected to deal with the typical marine environment found on small boats? I've never had serious problems with corrosion on my alternators, but they are attached to a big hot engine that periodically dries everything out. Is a salt air environment death for these electric motors?

This rings true to me. Author:

ď but the solar panels were indefinitely delayed because of Brexit, Covid and general global supply chain issues.

I reluctantly gave up on the idea of the solar panels and decided to buy a charger instead.

A proper Victron lithium battery charger costs around £1,000 and requires expensive cabling, and its own housing box on the boatís trailer, all of which pushed project costs up even further.Ē
All solar panels, in all of the UK, were indefinitely delayed? Sounds more like the ones he picked were out of stock so he gave up on the whole idea and moved on to the next shiny thing, which happened to be an overpriced charger setup.

Itís possible Iím wrong and there were functionally no options, I donít live there.

On the other hand, Oceanvoltís response is also surprisingly bad:

ď Moreover, we must highlight an issue concerning the sump bilge pumpís location beneath the motor.

This setup, inherited from the diesel engine configuration, raises environmental concerns.

Potential exposure of oil or harmful liquids in the bilge could lead to direct discharge into the sea.Ē
What are they even talking about? How is this relevant in any way?

Re: Electric Power a sobering story

Seems like it was a poor choice for that application.

It looks like an open cockpit where any water that comes into the boat from rain/sea flows directly into the bilge. And then the bilge was allowed to fill up with water - evident by the lower stainless mounting bolt with the rubber insulator being rusted. Not surprising that it corroded and failed.

My friend has had an electric motor (Electric Yacht?)for about three years now on her sailboat in a wet bilge/damp environment, leaky packing gland. It looks as good as the day it was installed.

Considering other electrical stuff lasts adequately on the boat, I'd think it's possible to make an electric propulsion setup last just fine with a bit of care. Make sure nothing can drip onto the installation, ventilation doesn't allow salt water to be splashed onto anything or excessive salt mist into the compartment. Shield it from any stuffing box drips or spray, etc.

Basically the same stuff that keeps an engine and its wiring happy and avoids it turning into a rusty lump with flaky electrical.
