>Do we have many documented conversions in the group?
The Honda 7.5 HP with my Electric Caik motor/Turquoise BLDC motor
controller worked nicely in February. Youtube - 3 short, low-rez
clips:
http://youtu.be/zrtE6yHSFRw - rundown of the setup
http://youtu.be/jen-WpfaM4k - pulling out
http://youtu.be/-L3yHhgoFmE - a bit more footage
See also my newsletters, esp. covering February. (Dec, Jan, covered
making the motor.)
I connected the motor straight to the shaft going down the leg with a
flex/joy coupling. Quiet, simple.
The main objection is the 2.7(?)-to-one prop speed reduction down in
the foot, limiting the prop RPM and the speed even on a small boat.
The greater torque of an electric motor goes to waste and (generally)
it doesn't reach the high RPMs of gas. I think this has been noted
before on this list as being a common problem for doing electric
conversions of gas outboards. I've seen a chain drive used to speed
up the drive shaft to compensate, with an 8 HP Mars motor. (In fact,
here's his video... http://www.youtube.com/watch?v=BP7LMbqV8Lc .)
Belt(s) would be quieter.
