Almost none of the motors that we are using in our conversions are specifically engineered for marine use. That said, we have thousands of hours of combined usage across conversions in this group and the lack of specific marine motors doesn't appear to be an issue. Virtually all of the motors that we use (Agni, Mars, ETEK, or other EV motors) will have different capacities depending on the installation, and the manufacturer has no incentive to try to guess how each of us may try to torture their product. You can imagine that an ETEK motor will have much better cooling mounted on a motorcycle than tucked in a box underneath your cockpit. I think that your best bet is to take advantage of the experience of the people here to figure out whether specific components have worked well in similar conversions. Of course, buying a complete system from one of our regular drive vendors will give you even more predictable results.
I've forgotten now, what kind of boat do you own? How soon do you expect start your conversion?
