  Electric Motor in Mk2 (PeterC)
Posted: 1:49:30 pm on 1/3/2014 Modified: Never
 
  I just installed an electric motor in my Mk2 ( the old Atomic 4 was long dead and siezed up). I used a 5KW motor kit from Thunderstruck and US27DC FLA batteries.Its only been a few days, but so far we just love it, lots of power, just turn the key and push the throttle to be away, such a change from using an outboard. The installation was fairly easy, about 15 hours work done over the Christmas holiday. The cost for the Thruderstruck kit and batteries came to US$3400.00. Not bad compared to the alternatives.

Hi.  Out of curiosity, may I ask what the speed and range is on battery?

Thanks.  Barry  Oasis, 1987 Mk V

Peter, I hope I will be able to say the same. A shipwright and I are building a system for my Paceship 29, (C&C 29), this winter! I'm using a 7.2 KW motor. Have you joined Electric Seas Forum, in your area of the world?

Barry,
 I'm depending on a performance spreadshhet I found on Thunderstruck's website. Speed in a huge factor. The numbers I am working on are;
   At 2 knots to 80% discharge  = 32 miles.
   At 3 knots ................  = 10 miles
   At 5 knots ................  = 3 miles.

 When sailing the spinning prop is supposed to give some re-charge. As I sail out on Santa Cruz there is always wind, except occasional winter days when there is a cold high pressure sitting on us.

No, havn't heard on Electric Seas, but I will check it out. I have joined the online forum "electricboats" on Yahoo, but I find it to be dominated by techies discussing topics such as how to build your own charger etc. A little beyond my level ........

I'm incorporating a folding prop into the system, because my Club is big into racing.
Your endurance can be increased by 50% by a Honda type generator, and wind recharging system, is seeing major price reductions.

Thanks.  Both the 2 knot and the 5 knot figures surprized me.  I knew there would be a big diference, but never thought it would be ten-fold.  Good luck with your system, and fair winds to you.

Peter, how much battery capacity do you have?  I see the "FLA" refers to flooded lead acid (deep cycle) type -- the site shows AGM and Li type... Assume you have 4 batteries, of 205 amp-hours each -- is that right?

Thanks

Yes it won't be "What's your RPM". It'll be "How many amps/hrs are you drawing"?
