Re: [electricboats] Draft Schematic-Please give input

For my suggested 48V-->96V "turbo solution" - I have to check the insurance terms, of course.

My boat is in EU, not USA. Maybe easier :-)

However, we still have 120/230V AC 10/16A running in our boats, right ?

Now considering :

48V/96V :

At 96V (just for motor power), I could buy and use a smaller (and cheaper) motor with a doubled gear reduction ratio.

A bit more more noisy. But "Whee-whee" could be the sound of the saved money ;-)

RPM :

The ME1616 (as an example) is actually made for 5000 RPM at 96V.

But we use it at 2500 RPM for our 48V systems.

How about a tailor-made EP marine motor, made specifically for 2500 RPM ?

Or, even better, a 800-1200 RPM motor for direct drive ?

I haven't found any by my searches, so far.

Yep, any marine drive system greater than 50V should consider the ABYC T-30 specifications.  If the installation meets these "higher voltage" system specifications, then an insurance company should not have a valid reason for declining coverage due to voltage.  Of course, in practice, they often decline coverage for a variety of unrealistic reasons.
