Why doesn't everyone do ram fill?

[PuraVida]

Adding 3 more pumps is definitely on my winter project list. Waiting 14 minutes for the Enzo's to fill gets old fast

I am very interested in this mod too. Curious if there is enough available power for the extra 33 total amps. Have you started any research on the project?

I tested out the fi23 back at wakefest. It is an awesome boat. However they still use pnp systems to fill bags. They use 4900 labs of ballast but only the hard tanks get quick fill. Also the fi is going to be expensive. The boat I tested was msrp at 123k. It is a huge disappointment when it came to money. Boats surfwake was monsterous though.

The way I understood it has 4K of ramfill and two 400lb bags.

Ramfill is cool and all. but I remember a morning on my buddy's centurion. The smaller lake was pure glass and I couldn't wait to wakeboard on it. Oh, but we had to fill the ramfill tanks. So we had to motor for like 90 seconds and destroy all my glass so I could have nice ballast to wakeboard on.

centurion has ramfill.
mb has gate valves.
has shown up on a couple of boats. same basic concept just different ways to reach the same result.
kinda surprised the new supra that I heard has hard tanks didn't install something like this. down side tho is if the gates stick open, your day is done. I have seen an mb have to load on a trailer as one of the gates stuck open and wouldn't drain. fun to watch a half-ballasted boat try to leave the water.

The SL has bags under the floor for the new subfloor ballast.

I am toying with this as well.. looking to add 3 king pumps... You would need to add a series of relays to active the pump in both directions... I am assuming a second battery would probably be smart.. There wouldnt be a drain on the main system as the relays would tell the pumps to start working off of the second battery.. There is a thread on hear that talks about relay wiring... You would need 2 relays for each pump one for fill and one for empty..... I have a '17 craz and there is plenty of room behind the storage walls to add the pumps.. the only question i would have is for the center tank and bow sac I guess you would have to hook the pump directly to the bow sac as the center hard tank doesnt have a second fill location... I would imagine the center and bow sac would have different fill times so that could cause one of the pumps to run while empty as the other is still working(assuming they are both wired together)

Don't forget to add some holes to the bottom of the boat as 1 will not feed 6 pumps.

that would be the next item to tackle, but is the factory only using 1 thru hull to feed 3 pumps currently?

[PuraVida]

I have 3 holes, one for each pump in a 16 mojo. Curious if you could run 2 pumps per hole without a major loss in flow. Anyone know how the 18s run the 6 pump system?

I seem to remember drew tinker making a comment on the Facebook page about this particular question. He basically said that through their testing, the 6 pumps will draw as much water as they need through the same three holes.

As for the IBS/ center tank. I was thinking I'd just run the center tank on the timed switch and then add a switch and pump dedicated to the IBS, then add one of those wakemakers inline ballast timers.
