Re: [electricboats] Pocket Trawler Electrification

I've looked everywhere but can't find detail specs on those pod units.

This is about as close as I get: ePropulsion Pod Drive 6.0 Evo - 9.9HP 6kW Electric Motor for Sailboats

And that vaguely indicates it's a 6kw motor operating from 39-60v Input Voltage.

Well, devil's in the details…it may well be that, yes, at 60v drive voltage you can get 6kw out of the motor continuous (or not?), but in your case your max pack voltage fully charged will be about 51v (assuming 16S config).  Lacking details on the motor, I'd guess top speed would be 5/6 the rated top speed for the motor and that power also would be about 5kw (assuming same load torque or current).  At the bottom end of your pack voltage, of course the power and speed available would be less.

Now maybe these are conservatively rated and that even at 39v the motor can deliver full rated speed, torque and power.  I wouldn't leave this up to chance or wishes though.

 

Best of luck-

Hi Carsten,

 

Scroll up one post and you'll see a photo of the boat and the original drawing of the layout.  It's a Ted Brewer design called Blue Hill.  27 feet long, 9 foot beam, 6000 lbs displacement.  It's currently way overpowered with a Yanmar 4JH3E, 54hp.  I reach max reasonable cruising speed (about 80% of hull speed) at 1800 rpm, and even with 2" sound insulation from SoundDown, it's still unpleasantly loud on the boat while cruising.

 

The electric conversion will solve the sound problem and should give me plenty of range for my cruising on Lake Michigan and Lake Huron.
