Re: 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.
