I have taken the standard one out and replaced it with a dual bilge pump setup from Wamiltons in mine. But I know others who are running only a single (no standard) and my flatmates are running the standard and dual's. So comes down to personal preference and riding style I guess. Let me know if you want to buy a single or dual setup from Wamiltons as I have a shipment leaving from there in the next week or so and could get it included.
I run a single rule 500 and got rid of the stock pos. just take out the stock one and epoxy a rule bilge in its place
i run a blowsion twin bilge bracket with 2 500gph Rule pumps. I also have the stock one (as the blowsion bracket still allows for it) .......no point in taking it out unless you need the space. I also have a scupper....but i wouldnt recommend one
Yip factory scavenger and 2 X rule 500. Don't see any point in taking the factory one out. Its more work I don't have to do, and the less water I have in my ski the better.
Ive got the factory scavenger, scupper and 1100 Rule. Im with knoxie on the scupper, i think your better off with dual pumps.
