Very interesting. Thanks for additional details. I am gaming out a very similar path.
Do you have any power curves for the ME1616 at 48V?
Can you re-post the specs on your boat? Type, Disp, LWL
I got these additional details on the ME1616 from Montenergy...
http://www.motenergy.com/brdcmo2.html
1) The ME1304 is rated for 200 amps continuous with water cooling, and 125 without water cooling.
2) The ME1616 is rated for 140 amps continuous without water cooling. This is a lower specification as compared to the ME1507, because the ME1507 has cooling fins on the external case, and the case is thinner, in direct contact with the windings and laminations.
3) We rate the ME1616 motor at 2 minutes, 600 amps. This is form a cold start. If the motor is already at maximum temperature, then this time and maximum current will be lower.
Thanks, Dan Pfeiffer
Thanks all for the feedback. I decided to follow the advice and use belt and toothed wheels to give me flexibility. I also have a variable pitch 19" prop so have adjustment there.
The ME1616 motor I'm told has max rpm of 1800rpm at 48V although Thunderstruck have unconfirmed feedback from a customer that 2200rpm has been achieved. Will experiment once installed and happy to share if anyone interested.
I also checked kit elec shop . com - they have very similar kits to Thunderstruck. However I found Thunderstrucks prices better even including shipping, which was incredibly quick.
Now to get the bracket made and install over the winter ready for testing in the spring._._,_._,_
