I understand what your saying. Sounds like the best plan of attack is to try and prevent so much water from getting in at all.
A 500 GPH pump makes a good utility pump to remove water from wash down and such but its hardly adequate to remove unexpected water. I've got an 1100 GPH pump in my 17' Outrage and taking a couple of consecutive waves over the transom is enough to keep my 1100 GPH pump running a couple of minutes. I'd have an even larger capacity pump if I could fit one. Being able to dewater fast is a good thing IMO especially when something unexpected happens. Years ago I had my Outrage completely swamped when a large rolling wake from a tug caught us off guard while anchored up fishing a bridge at night. The boat was very unstable full of water with two of us aboard and anchored up in a current. It was a tense 10 minutes or so until the smaller 500 GPH pump I had at the time finally got enough water out that the boat was stable. I installed the 1100 GPH pump after that incident and it makes a significant difference. My old 500 GPH pump used about 2 amps while running. My 1100 GPH pump draws just a bit over 3 amps. Not a lot more power consumption but significantly more effective capacity.
