First, electric motors generally don't mix well with wet bilges and their lifespan will be far shorter than you'd think.
Second, as PBZeer has pointed out, if you're running the motor directly off the genset, you lose most of the advantages of having an electric motor. Also, the idea of running it directly from a genset is not all that bright, since gensets loads are generally only for resistive loads—they're generally half as efficient for inductive loads. Also, most motors suitable for this type of work are probably 36 VDC or 48VDC and few gensets put out that much DC voltage.
Third, you'll still have all the problems of running a diesel with the added complexity of the electric motor setup. Your fuel efficiency will suffer seriously, since you now have the electric motor losses as well as the genset losses.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
