Looking for options to decrease my fill and empty time on my 2016 moomba mojo. My current system:

1100lb rear lockers
400lb under seats
700lb center hard tank
500lb bow sac

The 400lb sacs under the seats are piggy backed off the 1100s in the rear lockers. Each fill and drain through a factory stock Jabsco reversible pump, one for each side.

The bow sac is piggy backed off the center hard tank. This fills and drains through a single factory stock Jabsco reversible pump.

So basically I have 3 pumps total and the most one has to fill is 1500lbs. This takes roughly 14.5 min. I believe the factory stock pumps are the "Ballast Puppy" pumps. Would it be worth swapping these out for the "Ballast King" pumps? Could I add three more "puppy" pumps in parallel to decrease time? Is there any other options I am not seeing? I am not very comfortable drilling more holes in the boat but may entertain the idea if no other options make sense.
