2008 rz4 more ballast

[dan_allen472]

I have a 2008 rz4 with stock ballast. (tanks in rear and horseshoe bag in front.) I want to get at 2000Lbs what should i do for a setup? i wakeboard a lot but also surf aswell thanks

A Fly High W701 V-drive sac set for the rear and a W707 Fat sac for the walkway. That will give you about 2400 lbs total - 1300 front/1100 rear.

I would like to keep the bags hidden so I don't want any in the seating area at all. The
Front bag is a 2 compartment bag under the front seats( has 2 switches to fill front left and front right) so I would like to Remove that bag and put 2 bags on each side under the front seat, instead o the horseshoe wraps aolround the front under the seats. Which bags will be best for that. Thanks

Do you mean replace the bow sac with 2 sacs, one under each side, or 4 sacs, two under on each side?

With out doing a custom sac, the best sacs to replace the W711 Integrated bow sac, would be the W701 V-drive sac set. Although these sacs are rated at 400# each, I dont know how much more then 300# each they will fill do to the depth of the under-seat storage. The sacs are 16" tall.

Based on dimensions and rated weight, the W704 Tube sac is ideal, but the port placement is less then ideal for filling and venting. All 3 ports are on the same end. Turned one way, the sacs will fill drain fine, but not vent because the top port will be on the low end of the sac. Turned the other way, they will vent just right, but the drain is now on the upper end of the sac and water would be left in other end.

Do you have the optional bow filler cushion? If so, the W713 (a single W701) will fit almost perfectly under it. This has it pretty much out of sight.

Ya I'll just throw away the bow sack and I want 2 sacks o e on each side

what ratio should i try to keep for weight front compared to back? should i have more in the back then front? also i was reading on flyhighs website that there w711 inegrated bow sac is 725lbs and i believe my stock tige bow one is 400lbs is this correct?

The Tige V-drives like at least a 50/50, and a 60/40 front/rear is better.

yes, the Fly High W711 is rated at 725#, and should fill to at least 700#, if not full in your RZ4.

Is your current bow sac white with orange fittings, or is the sac gray? If it's white, it's the Tige sac, if it's gray, it's the Fly High W711.

Yes mine is the white bag. So it's 400lbs correct?

Yep, that's the Tige sac, and it's roughly 400#

i have read to different specs for my boat for ballast. one says it has 900lbs and the other says 1200lbs how much is the stock ballast on my rz4

I can't put the vdrive sacks because my compart has a step up in it because of the batteries
Both sides have the stepup what do I do?

They will go right in front of the battery box and stretch out under the seats a bit. Although the sac is 16" tall and the under-seat portion is only 12" high, the sacs will still fill to around 350# plus. If you want more weight back there then that, then step up to a pair of W707 Seat Bottom sacs. they will net you about 600# each.

whats the best prop for me to run on my boat or is the stock one good?

[skippabcool]

What is the prop that is on your boat? Most likely you will want to go to the 1235. You can either contact ACME or Chpthril. I would look to Chpthril to set you up, he can probably save you some money. I bought a custom sac and pump as well as a prop with weekender kit from Chpthril back in December. Easy process and completely happy, just need to wait for the weather so I can use them.
