A good hood seal, ratchet hood strap, blocked front hood holes, a 500gph rule, and stock siphon is all i run. Bilge pump doesnt even pump a lot when i go under. I ride 95% surf and so do my buddies who don't run scuppers either.
How much water are you really getting in your hull? If it's THAT much then you have to seal up a little better IMO.
