If this is for any purpose besides a temporary electric need like
powering Christmas lights for a one time boat parade I would suggest
rethinking your whole strategy.... or name me in your will....

portables and marine gensets have almost nothing in common, except the
fact that they both make power.

If it is for a one time activity on CALM water..... may I suggest you
put it on the SWIM platform (Fuel leaks can ruin your whole day... or
life) As far as grounding.... they usually have a grounding lug on them.
Just attach a wire from that lug to the ground of your boat. Not sure
why you would want to do that. you cannot combine power from multiple
gensets to power one large item. (Unless they are synced.... impossible
with a portable genset like you are talking about)
