Corrosion (and Component Quality, nowadays)

 

Seems that corrosion is an issue in the marine environment, if you haven't noticed.

In general, most engine tech for a boat is sold as "marine grade". There IS a reason.

Now we enter the EP world of new electronic components, mostly spinoffs from the EV world.

Many of you have been "electrified" for years, with genuine products.
Not cheap, but reliable.

The trend now is to make conversions as cheap as possible, using unknown, unproven and almost uninspected components coming from the middle kingdom.

The marine world must have RELIABLE components.
Where can they be made ?
USA and Europe gave it all away to the above mentioned country to make.
I have been supervising ship parts made by european makers. Top notch !
But - now the makers are all closed, just a few remains.
And, I have been supervising ship parts made by middle kingdom makers. Not top notch.

The nearest we can get to reliable parts and QC controls are Europe, USA, Australia, NZ, Taiwan, South Korea and Japan.
The benefit is, that you can even TALK to your supplier directly, if in trouble !!
In the middle kingdom, any questions you ask has to be passed to a manager at a higher level, be translated, replied, translated back, and finally you get just a "no" or a "yes" to your request.
Leaving you clueless...
If you hardly insist to solve your problem, further communication will take most of your valuable time.

If I CAN avoid it, I will not put any new and sensitive parts into my boat, that comes from sources that I can not call the design department by phone, and ask for a direct advice.

We can all go for it, and support the so called free world by this. (Was, until end of 2019.)
Pay more for the difference and the safer parts.?

Support the serious guys !
They need you badly !

You are a sailor.
No parking lots to save you on the water.

Just some thoughts...

These are rudimentary electrical in nature, not hit-tech embedded electronics. As for "racing sailboats with electronics" I am sure you are looking a mega dollars, not some crafted together electronics tied to aftermarket electric propulsion. Spend enough (as I mentioned in military grade or aviation), yes it can work mostly flawlessly.

Eric,
I concur.? Over 600 conversions on ocean going sailboats up to 40000lbs.? If you do it right with quality marine components you will have a safe and reliable system.? Yes you can cross oceans as I am aware of many blue water cruisers with 1000's of open blue water sailing.? Some Volvo Vendee racers have electric propulsion.?

I look at sailboats as compromise and recommend sailors select what is the best for them and their sailing agenda.

I actually do understand purest who do not have any propulsion systems on their sailboats but sails. But there is not a diesel or gas powered sailboat that does absolutely depend on electric motors.? They are the most reliable motors on the boat.? Unless you hand crank the diesels (no electric starter), gravity fed fuel (no electric fuel pump) hand bilge pumps (no electric bilge pumps),? And who does not say a short prayer "Lord please let it start" when you need an emergency start of a diesel.

Just saying,.
