So I replaced my old system with the upgraded wakemakers reversible pumps on my 07 LSV. It really isn't a tough job, just take a little time is all. I reused the original through hull for one bag and then drilled 2 new ones for the other two pumps. I ran one pump to the bag in the floor of the boat (ski locker) and then ran another hose from that bag (the vent line) up to the IBS bag in the bow to fill it. Then I ran a vent line from the IBS out the side of the bag where the old vent was. Hopefully that makes sense. I mounted all 3 pumps in the engine compartment which was pretty easy. I can take pictures if you want to see where they are. The electrical switches are pretty easy to connect as well. I love the system and think it's a great upgrade.
