125A x 12V = 1.5kw
Enough to cause a fire, but not enough to drive your boat.
Just ask yourself: Do you have experts for electric drives around? if not think about who will install it and fix it in case of trouble.
In my part of the world running a boat for business would require all components to be tested / certified /etc. No funny
experiments with other peoples lives.
I really like the idea of electric drives but they still have a very marginal market share - so small I consider them experimental. More adventurous natures may disagree but since you are talking about business use I guess your prime concern is reliability
If you simply want low cost reliable propulsion go for standard diesels.
