Re: [electricboats] Elco outboards

Neil,
Are there more details available on the boat you will be putting these on?

I would be very skeptical of getting the speeds you're looking for with an electric outboard, and would strongly suggest you try one motor first.

I don't have experience with Elco's, but have tried the 48V Torqeedo.
Back of the envelope - 48V x 125Ah =~ 6000WH.
Assuming the engine will burn 3000-4000W at high speed, you'll have less than 2 hours run time - especially if you want to have a reserve.  After that, there will be a significantly longer charge time.

Will this be a "rental fleet"?  What is the usage model?

I'm considering powering my new Lillistone Fleet build with an Elco EP-9.9 outboard. Battery bank will be 48V 125Ah LiFePO4.

Anybody have any experience with these motors? Particularly in a semi-planing application? (Fleet will do 11+mph with a 4hp gas outboard and two adults aboard, over 20mph with a 9.9 gas outboard.)

Reliability, efficiency, repairability?

Thanks!
Neil
