Replace Atomic 4 with Electric Motor?

I am completing the refit of a 1974 Seafarer 34’ ketch that I acquired from a gentleman who couldn’t complete it. I wanted to install a generator of sufficient size to provide the comforts of air conditioning and a refer. I know generators can be had that are not real heavy and would work for my needs but I have a 4 cylinder diesel 20Kw Onan marine generator I bought for another project I’d like to use. It occurred to me I could pull the Atomic 4 and replace it with the Onan and an electric motor.

I haven’t done a lot of reading on the electric motors (yet). What are the pros and cons with the electric motors? I’m guessing I won’t be able to pick up parts at the local marina like I can for the Atomic 4, but other than that what should I look for?
Since the motors are electric, is there just a switch to reverse polarity so I won’t need a transmission (more weight savings)?

Full of questions (and other stuff), not many answers, so – bring it on! 8~)
