Depending on what you have I would be somewhat cautious about installing a forward scoop on the generator.  I had a 1988 33 Open and the previous owner had retro fitted a Westerbeke with a forward facing pick up.  If the sea cock was open underway without the generator running it would force water past the water pump into the generator.  The Westerbeke needed the exhaust pressure while running to force the cooling water through the system and if it wasn't running water would fill the engine through the open exhaust valves.  This may have been specific to the Westerbeke but I know the owners manual specifically stated not to install a scoop through hull.

I should note this is not a problem on my 41 Open with an Onan generator
