View Full Version : X45 Ballast Question

05-09-2011, 11:28 AM
Hey guys. New here so appreciate any help yall can give.

I have just purchased a 2008 X-45. This past weekend I started experiencing trouble with the ballast filling and emptying. It seems like the pump would turn on for about 10 seconds then shut off. I had to keep turning off and on to empty completely. How do you reset the pump timers when it is in this mode?

I thought there may be trash or something in the lines blocking the pumps. I opened up one of the pumps and saw that it has the Yellow impeller. Looked basically brand new. However, reading posts on here, I have gone ahead and ordered the green impellers and will swap all out this weekend and see if this helps.

Also, I am interested in adding some sacs in the rear lockers and bow lockers. Not really ready to spend 1300 on the integration package so wanted to see about putting 2 of these piggybacks in the rear.http://www.wakemakers.com/mastercraft-piggyback-750-ballast-system.html Will this work for my setup? How would I go about doing this for the front?

This happened to me last year. I was told by a dealer to run the pumps for the duration of their cycle so the timing is reset. Worked for me. The ballast actually have timers on them, so if you're jockeying around with them (on and off, on and off), it will throw the timers off.

so after the pumps have turned off automatically, keep the pump switches turned on for an additional cycle to reset the timer?

im not familiar with the x45 stock setup, but i removed the tanks / bags in my X1 and hooked up 750lbs sacs to the stock hardware / pumps.



check out www.wakemakers.com they have everything you would need. I bought 4 screw in adaptors, and 4 quick release elbows. works great!

Exactly. Like I said, it worked for me. I was told to do this by a very knowledgeable member of this forum, so it comes from a good source.

As for the ballast on/off question, this happens to me once every few weeks. Keep turning it on off until its completely empty and when empty let it sit for 3-4 mins in the off position. This will usually reset the timing.

As for ballasts, I recommend these for the rear compartments.


I used to have 3rd of the same sac on the bow floor. But now that I've gotten a second pair of the v-drives I have one in each blow locker, filled about 1/3 full so they fit under the seats. That plus the stock system on a 45 throws a great wake.

roger that. thanks!
mpabreo do you have it automated or do you pull out a pump each time?

how big are the compartments on the x45? If they are bigger than the x1 i would get the 750s...

750's more than fit in the rear lockers. Quite a bit of room left too.

05-09-2011, 02:24 PM
yea i was gonna say, cause they fit in the X1 lockers and those have to be tiny...

Mine are not plumbed. I pump out about once every week or two. My boat stays on a lift with ballasts full so I can drop her in get a set and be done quickly so hard piping has little benefit for me.

As noted by the others, the 750s would be even better, just make sure you weight the front enough.

so i did the rear piggy back upgrade from wakemakers this weekend and it went pretty flawlessly...went with the v drive sacs set(800 lbs total).....however the original overflow hose seems to be a bit short to connect to the sac in the rear locker and needs to be extended...what do yall suggest getting to extend this hose? i'm assuming i just need http://www.wakemakers.com/1-hose-barb-union.html or should i replace the whole hose?

i was able to reprogram the starboard pump fine but the port pump wasn't as successful....cuts off at 2 1/2 mins even though it blinked 10 times in the programming...will have to try reprogramming again next weekend

i can't decide if i want to put these v drive sacs up in the front and get 750 sacs for the back...the v drive sacs seem to fit well in the locker now and give me a little bit of storage still in the back...i'm also concerned on the bags pushing against the other cables/wiring/hoses in the lockers

i'm ready to do the front piggy back system now as well...im either gonna purchase another v drive set and fill it partially or buy the 750's for the rear and use the v drive set i already have...now i think all i have to do is T off the KGB overflow and run hoses to the left and right locker then run an overflow from one of the bags to the existing overflow...i would assume i need to use the left bag or does it matter? see image if I didn't word it right...how much hose do you think i need to buy?


05-24-2011, 01:03 PM
with me only partially filling the 2 bags up front I'm thinking it won't matter where I put the overflow since I will never overflow...so putting it on the right will save me some hose as well right?

This might help

getting ready to do the front ballast upgrade this weekend! parts coming in thursday! I'm pretty excited!

ended up going with nautique wedge sac set for the lockers. I plan to T off the KGB overflow then run to the left and right locker sacs and then connect the original KGB overflow hose to the right locker sac. Will this setup work or will I risk popping the left locker since it doesn't technically have an overflow? I was thinking since they both "should" be filling up at the same rate they both should be full at the same time

minor concern- Should I try and relocate the amps in the port locker? I'm concerned about the sacs possibly popping at some point and ruining the amps...or is this highly unlikely?

EDIT: reading up on some other posts it looks like I'm gonna want to vent the left sac to the right sac and I shouldn't have any issues

so I finished the front ballast upgrade yesterday. well almost...I need to order two fittings to complete the venting from left to right sac. here are some pics :)

KGB overflow cut and T'd to Port and Starboard
Original KGB overflow rerouted to overflow in Starboard Locker

The timers are a real pain for you can take them out and replace them with a timer that will will not time out. The switch is $100 for each pump. You can call 800 625 9666 and they can sell them to you at Mid West MasterCraft.www.waterskis.com. Corey there is very helpful and they get me parts back to NC very promptly. They will even send you a picture of the module you are buying. I have an X-1 and while we have not changed the timers out and all of the suggestions I am reading generally work they still have to be reset all the time. I am getting a X-45 in about 2 weeks so I am leaving it as is in the X-1. The newer X-45's are built with plug and play as an option without timers, however they are not vented, the bags dont come with it.

Now my son is extremly curious how is the wake behind the X-45 vs the X-Star and X-25. How much weight is anybody running. We currently put alomst 3000 lbs in the X-1 so he likes it big to say the least. Any comments are appreciated.

The first mod you should do with a MC is bypass the timers.

06-11-2011, 10:44 PM
It has taken us a few summers to dial this in....The best configuration we have come up with:

07 X45

1. Move batteries to starboard bow in front of cockpit.
2. Use 400 lbs of pop bags spread across floor of port side to make up for loss of ballast when repositioning the batteries.
3. 750 FH piggy backed in port locker.
4. 1000 FH under port cooler seat, runs 10 feet towards bow. (Custom made from Wake Makers, dedicated pump, uptake, and vent).
5. 400 FH half way up on port sunpad.

Approximately 3200 lbs with stock port and KGB.
Move pop bags aft if you want steeper. Forward for length. Also move peeps as necessary.

Trim full up. Perfect Pass at 11.0-11.5 calibrated with GPS.

nice wave dude...i'll have to get pics of mine next weekend...I'm loving it so far

the timers are definitely pissing me off...gonna reprogram them to the max limit and if I have anymore problems I'm gonna do the bypass

Is the ballast set up the same for an X-Star? I was unaware of timers. I have allways filled all the ballast up to F and spitting out the side of the boat then I turn them off. I have a 07 and I would say I have the same issue, as far as emptying. It seems I have to turn on and off to get to E. But I am not sure if they will automatically shut off. When the gauge gets close to E the switch will start flashing and I have assumed that is when to turn them off. Im not sure.
