We have a similar size/ weight boat, so interested in what speeds you get with the old motors and new.
We are thinking of thunderstruck 10kW's at 48V, or even the motenergy me1002 to allow some short distance speed/power. The Oceanvolt quote was...interesting!

Hi The most obvious choice for value is 2 x 5kw Sailboat Kits from Thunderstruck. That will give you a lot more power then the Pactorq set up. If you have a 144 volt battery bank connect in series and parallel to drop it down to a much safer 48 volt system. I assume it is shaft drive with a gearbox or some other type of reduction. You may be able to use the existing shafts and props. We need to know the prop diameters and pitch to suggest a suitable reduction to the prop shaft.On Sat, Jul 27, 2019 at 2:33 PM sailorboy55577@yahoo.com [electricboats] <electricboats@yahoogroups.com> wrote:Bought an older Sail Craft catamaran powered with Pactorq servo brushless dc motors, 144volt, I lost commutation in one motor and through the process found out their obsolete. I'm looking to replace the set, I see there are many options available, just thought I'd put it out there if someone has the wisdom to recommend a suitable replacement. 14000lbs displacement, 44 ft long, 3.5 ft draft.
