Ran mine for a season without the genny installed. The stern was a little bit higher but I don't recall any dicey situations. The Approx weight per specs is 420#. If you're running inlets you might want to add / replace the weight back there as a following sea can creep up on you.

Mine used to have a genny and it was removed before i bought it. Boat sits with a very slight list because of where the old generator batteries were located. No handling issues whatsoever.
