  • Extra Ballast Bags in XT22

    I have seen that most people seem to be adding lead weight to their XT boats. Has anyone else considered added extra bags under the seats below the tower legs?
    I figured if I had bags instead of lead, I would generally keep them full, but it would only take 10 minutes or so to throw a Tsunami pump on to empty them. I would then have the ability to take someone for a ski on the odd occasion.
    I have already asked in the XT22 thread for locker dimensions (no-one has got back to me yet) It looks like I will be unable to get to my boat for maybe another month, so I would appreciate it if someone could grab a tape measure and let me know how much room is beneath the seat where the cooler lives. I am going to leave the cooler out. I am not able to order bags until I get these measurements.

    Hey Malles. Can't help but very interested in how this works out for you. Hopefully someone will help you with the dimensions. I assume its winter for you so you can't get to your boat. Please post what size and weight you're able to add when you get it finished.

      Hey Wallos, yeah, its winter here and we are also in lockdown again so not able to go that far to measure myself. Big shout-out to my local dealer @mastercraftmelbourne who rang one of his customers to get the details for me. I ordered a couple bags from Wakemakers yesterday. When installed I will have an extra 610lbs per side (if I can fill them completely). It sounds like most people are only adding 1000lbs extra so I should be good to go. I also have another 400lb of lead that I can use if needed. The plan is to install 2 new thru hull inlets and 2 new thru hull vents. I've also purchased the fastfill pumps for the rear tanks/bags, as well as some high current relays to drive them. I plan to repurpose the original pumps to fill the new sacks. I'm not keen on leaving my boat on the trailer with 1000lbs of lead, so this will give me a lot more flexibility by being able to empty everything out each time.

        Mallees, that's great to hear. What was the dimensions and what bags did you pick? Extra 1200 lbs as an option to lead sounds good.

          Hey Wallos, I picked a pair of the WakeMAKERS UniversalFIT Rear Locker Ballast Bags. Bag Size 40"L x 25"W x 15"H - 610lbs They haven't shipped yet, but I'm hoping one will pretty much completely fill the cooler locker, and there is obviously heaps of room in the coffin locker, really looking forward to getting it all plumbed in. I'm still undecided where to install the new switches, that's the problem with these new boats , I can't just add an extra couple switches to the touch screen unfortunately. (It would be nice to have the programming software for the screen) The fast fill pumps should be pretty straight forward, I've ordered a couple 4x4 winch relays to handle switching the extra current of the fast fill pumps.

            Depending on winch relays you got they may not last long. I did a lot of research into the proper relays to handle the amperage of fast fill pumps. I would piggyback the bag vent to new bag inlet and then vent out. If you wanted dedicated fill empty for those bags then I would make a bracket off the phone holder for them. If you need help with wiring the pumps just ask

              Hey Wakejunkie, the winch relays a purchased are rated at 100amp continuous duty and have an electrical life of min 50,000 operations, so I'm hoping they outlast me, . The reason I went down this path is purely lack of space. I was originally going to do the same as you with 2 solenoids per pump, but now that I'm installing an extra 2 pumps I would require a total of 8 solenoids. The plan is to mount a panel with 4 winch relays and a fuse block near the batteries, that way I'll only need to run small control cables from original pump connectors to control the big pumps, and a couple small 3 core flexes from the new switches to control the repurposed pumps. I'll also run some 6mm2 cable to all 4 pumps from the relays. Slight overkill for the ballast puppies, but just trying to keep it uniform. I also considered teeing in to the existing vent line, but then I'd need non-return valves. I really want to be able to see when the new bags are full, so I can turn them off.
              Also, thanks heaps for the offer on help with wiring, I'm pretty sure I have it covered but I'll be sure to call upon you if I have any questions.

                The new bags are way smaller than stock rear system so with fast fill pumps it will be full in 2 minutes tops. I would replace factory rears for fast fill and move stock pumps to added bags. Then everything will be sub 5 minutes. I looked into winch relays and though they were rated continuous duty it was only for 1-2 minutes. If the pumps run longer the relays build heat and fail. Just a heads up if they act up. I meant the additional switches I would mount off the phone holder. Here’s a pic of the dual 1.5” intake valve

                  Sorry I thought I said that. I am going to use the stock pumps for the new bags. I’ve actually put a hold on the bags as I’m hoping I can get bigger ones. I never actually got an accurate width measurement for the cooler locker. We’ve been in Civid lockdown for the last few weeks so I haven’t been able to get to my boat, but that has changed today so I’ll be going to the cabin this weekend to get accurate dimensions. I see what you mean about the relays, hmmm I’ll keep an eye on them. If they start getting too hot, I may have to change over to solenoids, but I really don’t have any room. I purchased a battery charger from the states without thinking about supply voltage. [emoji1750]. So I had to buy a 240/120 volt transformer to fix that mistake. This takes up most of the room behind the batteries. For the cost of the relays, I’m not going to go broke if I need to replace them every couple years ( hopefully they last that long). That dual intake looks the goods, I’m actually thinking of not increasing the suction size initially purely to ensure I don’t crack the hard tanks.

                    Hi Mallees, got the same boat 2018 edition here is Aus also so interested in this mod, are u unhappy with the wave of just looking to further improve it ? Are you going to be able to up size the inlets to the factory rear tanks to go with the fast fill pumps, have you looked at upsizing the factory rear bags as if I recall some other posts here the factory ones are not the biggest you can go but it depend something on the rear lockers as there was a slight difference between some XT 22s and other XT22's if I remember those posts correctly.

                      I saw you asking for dimensions but I haven’t been around my boat in last couple weeks to measure. I think someone did 400 pound bags in that cooler area on a 23. The relays can mount behind the port ballast panel. Plenty of room for stuff in that area. The tanks shouldn’t crack at all. They’re designed for 1.5” fast fill. You shouldn’t need to upsize the pickup fitting. I’m testing it to see if there is any difference with it to stock. You should change all the stuff to 1.5” with the new pumps.

                        Hey Wakejunkie, I actually called into my dealer today and did the measurements myself, so I've just emailed Wakemakers hoping to change the bags before they ship. I've worked out I can get a 50"x25"x15" bag in the cooler locker, it wont be able to completely fill as the locker is only about 13" deep in most parts, but should be able to get a bit over 700lbs in there. I'll also put a 35"x25"x20" 710lb bag in the coffin locker.
                        I have only spent a couple hours in my boat so I don't even know where the port ballast panel is. I think you're right, I will most likely upgrade the hoses to both back tanks to 1.5".
                        I'm just trying to get all the upgrades done before our weather warms up. I don't want to be working on it during spring.

                          Hey Jason, don't get me wrong, I love this boat, the wake is good, but it isn't great with stock ballast. We haven't done much surfing in the past so I'm only really concerned with the wakeboard wake. Because its a pretty mellow shape, the more weight you add, the bigger and firmer it gets. I've only put 5 hours on the boat so I've only had the chance to slam it once, we had full stock ballast and about 1000lbs of lead and 6 people in the boat and the wake was really good, but I could tell by the shape that it will just keep getting bigger with more weight. I think I will end up putting 1.5" hoses for the fastfill, it sounds like the way to go. As for the rear sacks, I don't think we would gain a lot with bigger bags in the rear, the locker is already pretty full, I think I'll just put a 200lbs of lead under each sack. I'm hoping to have between 1800 and 2000lbs on top of stock to be available if needed. So just over 2.1 metric tonne.

                            That’s going to be some serious weight if you already have 1000 lead! My boat with 900 over stock ballast with 15x13 prop doesn’t like to get on plane to wakeboard speed but does. I hope you have the 6.2 for that weight and prop!

                            Yes I would do the full fast fill upgrade to rear including bags. I did my upgrade during the winter before spring so fully understand trying to get all the parts now. The panel is the carpeted rear piece that holds bag on top of the tank. Comes out with 3 screws. Here’s a picture of mine.

                              I haven’t got 1000 in lead. I had borrowed that just to try out. I only have about 400 in lead. With the new bags I should have about 1800 over stock total. But we normally only have a small crew. I’ve got the 5.3 and have not had any issues planing yet with triple launch. But as I said, I’m still learning this boat. I’d rather have too much than not enough, I can always empty a bit out. Now I know what you mean about the port ballast panel. I thought you were referring to an existing electrical panel. Do you have trouble removing that panel with cables attached?
