Multiple bilge pump holes on one side - proximity

[bigeasy1]

I did the same as hermit.A 2000 and a 1500 gph pumps with outlets on one side, zero problems.I took an additional small 500 gph pump and mounted it on a stip of aluminum flat, and slid it all the way back against the transom face and under the engines oil pan (I/O) so that I can get all the water out of the bilge
I cant see how two outlets would make any significant weak spots in the hull, especially way up high where your outlets are.I wouldnt lose any sleep over it.

I put the outlet for the pump that is on constant auto on one side so if I see that is comes on there is a problem that needs immediate attention. This pump was also mounted a little further forward than the other pumps.
