Hi southbound,
I've recently pulled my moody atomic 4 and put in an
electric motor. The
motor I went with was made by electric yacht. I have yet to change my prop over because I wanted to first see the
boats performance with the old one. I can get a max speed of about 4.5knots, where as I could get around 6.5 - 7 knots under
power with the atomic 4. I think I am going to have to go with a bigger prop because of the lower rpms of the motor. I believe the data you require to properly size your prop is the optimal rpms of the motor, the optimal power of the motor and the
displacement of your
boat. I am still
learning as I go, so I hope I am going to learn a few things from this thread as well. Anyhow, i find the motor so far to operate really well. The increase in control in tight areas is great so is the
reliability and not having gas onboard gives me a lot of peace of mind. So many pros with only the range issue as being the con, but I feel this can be worked around. anyhow, hope it works well for you. If you have any questions please feel free to ask.
