The wakeboard wake is clean on both sides even at slow speeds. Haven’t rode it yet to comment on how it actually performs.

I may have seen where people drilled holes in the divider panels and piggy backed 750lb sacks in the storage areas in the cockpit area. These piggy backed bags connected to the rear bags and allowed you to fill these bags with the current plumbing, making a total of 4500lbs ballast. Of course, we would warn you to never exceed your coast guard capacity, but if you were only running a few passengers, then you should be good to go.

This is another area where the new draft sensor can help you out. When the draft sensor maxes out on the display, the system thinks you have reached max capacity. But until you have a total of 5500lbs of ballast,passengers,gear, you shouldn't see that draft sensor maxed out. But with the extra weight, you will see an amazing wave or wake. Also, as mentioned before, by adding this additional ballast to the middle of the boat, it displaces the whole boat still allowing AutoWake to easily maintain the proper pitch and roll to maximize all displacement. By adding weight to only the rear or the front, it makes it much harder for AutoWake to maintain the proper pitch or roll.

Hope that helps.

Happy Sunday. This comment is 100% correct. There is no bow ballast option in the Max for 2018. The three giant 1000 lb. bags do well. I am working on custom WakeMAKERS under seat bags that will connect to the factory rear bags. You will need to cut a couple holes in the divider between the rear locker and under seat area. I will find out the best location and make a little cut template for it. I am also going to see if a different size bag in the rear lockers is worth it.

This is one boat that you should order with the 6 ballast pumps due to its capacity and autowake. I am very excited to get the Max dialed. It is an awesome boat that in my opinion competes with those twice the price. That is still hard for me to wrap my wind around. HAHA. PM me if any of you guys take delivery of a new Max soon. I would love to get some bags in the boat for testing. Have a great day.

What do you think you can put in the back of those lockers - size wise?

Wouldn't you need more in the front to offset that weight?

Very rough dimensions and does not account for shape of the space.

43 inches long (has a divider at the top that drops this to 35 inches

27 inches wide at the top (hull tapers in as it moves down)

41 inches deep

So three dead bodies in each locker :o

That’s what I’m thinking, lots of bodies.

Should be interesting to see what WakeMAKERS come up with.

Hey guys. I would recommend spending the majority of the time getting the middle bags correct. You could probably add a few hundred pounds to the rear bags, but if you make the rear bags any bigger, then you will not be able to use the current drop in trays that go over the factory rear bags. Granted, you might not want to use the rear drop in trays, but after using the boat quite a bit, I HIGHLY recommend the drop in trays. It is hard to visualize just how deep those rear storage compartments are. IF you actually put anything into those compartments like a jacket or something, and then drain the ballast, you physically have to get in the rear compartment to get it. You can NOT lean over and actually reach the bottom and this is where those drop in trays really come in handy. The trays are deep enough to hold all the life jackets, ropes, buoys you would need and you can still access them when the ballast is full or empty. Again, I have used other boats with "subfloor" ballast, but even in those, getting items out of the rear storage is NOT easy, especially if you don't have good dividers in them.

One thing you will need in comparison to the current factory rear bags is an outlet (preferably) 2 on the front of the rear bag to then piggy back into preferably 2 inputs on the middle bag. You can get away with just 1 fitting between the bags, but if you have the 6 pumps, the 2 outlets in the back bag will drain the rear bag before the middle bag can fully drain into the rear bag. As an fyi, I am hoping we change this mid year or in 2019, but just giving you a heads up IF you decided to customize your ballast. Again, with 4500lbs of ballast and 4 or 5 passengers in the boat, I think you will be blown away with the performance.

So are you saying that if you want to piggyback some mid-under seat ballast into the rear bags, that it'd be best to get new custom rear bags with more ports so that the mid bags have the ability to flow into the rear bags? Because the stock rear bags aren't gonna have those extra ports for piggybacking currently?

That is what I am unofficially saying...

That’s how I read it and Incan confirm that there are not any extra ports in the rear bags now.

From the limited time on the water I can see what Goose. The boat already sits low in the rear at surf speed. I think adding the weight further forward would be a really good thing.

I still think ya'll need to make drop in trays for the Mojo that fit over the surf max bags. I know they wont be as deep as the max but 3 trays 3" deep will hold all my ropes, my box anchor, my inflatable bumpers and possibly 1-2 life jackets still. The will basically empty all the area under my cabin seats for ballast bags. Bulk of the life jackets reside under the bow filler cushion. Please oh pretty please!

Amen David! I was recently in a buddies Malibu and those trays were awesome. I also noticed small holes on back of rear deck cushions so they could drain. Another winner idea.

Are these stock on the MAX? During my build I didn't see a place to add trays...

I am curious as well. My Max only has the drop in tray over the engine but nothing in the rear lockers.

I could live with just a warming tray over the engine, having locker trays would be perfect for ropes and wet stuff.

Matt (goose) had said they were optional. but I agree, no place to order that option that I saw?

Hey guys. It appears the side storage trays are NOT on the online configurator, but they are on Dealers Circle which is where the dealers physically order the boats. I will see what I can do about adding to the online boat builder. As to the other models, we are looking to see where we can add trays. As you know, on many models there really isn't much depth to add a tray, but we will continue to look into it. Like I said, I used the side trays and center trays most of the season. I am a huge fan and hopefully we will continue to do more in this direction in years to come...

Goose may advise against it but I cut some access holes in the divider panels so I can reach the release latches without removing the center tray. The center tray does not come out easily without removing an engine cover strut. This makes it quick and easy to get to the drain plugs/oil filter, and dipstick.https://uploads.tapatalk-cdn.com/201...6492833e6c.jpg
The center tray is deep enough to store my swivel board racks plus ropes and jackets. I feel that having the racks out of the elements will help to preserve the rubber.https://uploads.tapatalk-cdn.com/201...e3a3bbdd34.jpg

Even at like 3-4" deep it would still clear out everything i have under my seats in the cabin and be worth every penny. I plan to take some measurements and look into getting some 3D printed but it would be way better for SC to do the work for me and I can just write a check!

Following the urban legend that Goose mentioned. Going the route of piggybacking ballast bags under the side seats. Went with some slightly larger rear bags from WakeMAKERS with available front ports to allow for connecting the rear locker and under seat ballast bags. I’ll report back after a test run(hopefully this weekend).

Will have about 4660 in water weight and around 750lbs of available lead to move around. Net 5410lbs.

Fairly simple upgrade with a couple of 2” holes in the divider panels between the lockers and the under seat areas that are recessed down to the hull. I also had to reroute the line from one of the Jabsco pumps on each side to accommodate for the narrower placement of the dual fill/drain ports on the rear of the locker bags from WakeMAKERS.

I used a Y connector to connect the vent from the new under seat bag to the existing rear bag vent thru the side of the hull. Hopefully this works out OK. Also adjusted the ballast timers to a best guess time. https://uploads.tapatalk-cdn.com/201...219dd6eca0.jpghttps://uploads.tapatalk-cdn.com/201...62d23bba6a.jpghttps://uploads.tapatalk-cdn.com/201...2d592241b8.jpg

That's some serious weight! Can't wait to see the end result.

That is some weight!! I will be waiting for the pics.

You get that MAX out of what... Let's see some results :D

I’ll post more later including some videos but the additional weight made the wave come alive. Did not ride goofy or spend any time wakeboarding.

The new setup worked great. Filled and drained with no problem. I adjusted the ballast timers and Autowake seemed to work it’s magic. I did not really have time to play with the setup and try to fine tune it.

We were on Lake Perris in Perris, CA. The boat is home for the winter and then going back to Lake Mead.

I’ve always wondered what part of the country and in what lakes you can truly boat year around without too much of a harsh environment.

Those of us from the Midwest can easily travel to the desert southwest, like the Phoenix area. But I was wondering if a boating life is possible around there as a winter tourist.

We've surfed that lake w/ Jeff from Soulcraft. Stayed tucked up against that rock wall on the southwest side of the lake. It was tough to keep away the lake lice away, but we had a great time!

It’s much better during the off season. So much less traffic.

So was it necessary to replace the rear bags to accommodate the piggybacking? (i.e. did the stock rear bags not have enough ports to facilitate the connections?)

Also, what bags did you go with for the underseat bags?

Where did you end up putting your lead?
