Thanks Matt , side question , on the ballast timers is there a way to get them above 15 min , that is the highest my crazy will go , have heard of Mojo's going higher but 15 min is max I can set mine to. Thanks

15 is the max my 17 mojo will go. Thinking about going the g6 route....

Was debating on that as well, already have the relay box planed out for adding pumps, but id rather spend the money on the bigger bags first. and ballast fill is the kid swim and our sit an relax time,so having high fill times doesn't bother me , at least for now and Craz not crazy, on previous post

You can flick the pump switch off and on again when it hits 100% to add another minute.

I went and looked and you are correct, the highest fill and drain time is 15 minutes. Stazi is correct that you can always overfill also. However, if you need to fill for more than 15 minutes, I am thinking you might want to check your impellor, or try filling with the engine on. The Jabsco pumps are impellor pumps so the speed of the pump has a lot to do with condition of impellor. The other main factor with speed is the voltage that the pump sees. When the engine is on and alternator is charging the system, the voltage of the battery should be between 12.5 and 13.5. As with any DC motor, the system will operate much faster at 13 volts, than it would at 10.5 or 11 volts. In a perfect state, those pumps should be able to pump somewhere between 90-100lbs per minute. If it is taking you over 15 minutes to fill 1100lbs, then you are only filling about 70-75lbs per minute. You might check impellor and voltage first and see if that doesn't improve the system.

As to why the timers are limited at 15 minutes, honestly I don't know. I guess we never thought we would need to fill longer than that so in our testing we didn't see that to be an issue. I guess we could go back and change software, but we are trying to make systems faster and with the 6 pumps system, you definitely don't need anywhere near 15 minutes.

Hope that helps.

I need more than 15 minutes to fill the center tank and now bag combo from the factory. My boat only has 81hrs on it so I doubt the impellers are already shot, but it could be that we often turn off the boat when we reach our start point and are filling bags so that we aren't logging hours, sitting and idling.

Faster is always better Matt, was going to integrate more bags to go under the seats, currently it is not an issue ,with 1140 rears it takes 13:40 to fill, which is about right, but if I wanted extend under the seat with bigger bags, I would need more time on timers, or faster pumps, agreed with the 6 pump wouldn't need it , but I don't have the 6 pumps system, was just weighing options, if I could get more time on timers would just do the bag upgrade until could afford more pumps, if its not an option, then will add the pumps first and do bags later. As well as Stazi , my front is set at 15min has been close to that since new, only have 70 hours on boat, and 30 plus didn't even use ballast. I did notice the bump the switch for more time, used that for the front last weekend,

I understand. That all makes sense. The factory default time for the front in 2017 with tank and bag is 11 min 30 sec. But it sounds like that is not working for you or Stazi. I am curious, do either of you have dual batteries in your boat and if so, where do you run your switch? Also, do you recharge your batteries often? I personally always run my switch in the "both" position and we keep the R&D boats batteries charged fairly often. Even if filling with engine off (which you can't do in 2018 ), it gives me a little extra battery bank to hold a slightly higher voltage. The front Craz has a 700lb tank and the bag is about 500lbs. So, if completely full it is about 1200lbs. 11min and 30sec was probably not enough time, but again if you are filling for 15min and not filling 1200lbs, then you are filling in the 80lb per minute or less range. I am just curious if maybe you are just filling at a lower voltage and that is why it is taking longer...

Regardless, I will ask about adding more time on the ballast timers. Like I said, we are still working on the 2017 field fix so we can probably get the extra long timers added to that. Unfortunately we will probably still want to put a cap of some type on it. You have got to see our side of the liability part and if someone flipped the switch to fill, but the bag wasn't connected, we couldn't have an unlimited timer on there. That would basically sink the boat. Especially considering that the ballast fills MUCH faster than the bilge pump can keep up. ESPECIALLY if someone did upgrade to 6 pumps and still had higher timers. Currently if you had 6 pumps filling approximately 90lbs per minute and you didn't have bags, in 15 minutes you would have pumped in over 8000lbs of water in the boat. I think anyone could see where that could be an issue....

I will see what I can do...

Definitely makes sense , I fill with engine off , key on and battery switch on 1 most of the time, but even when idling its close to the same amount of time, just figured for the front as far as the water has to travel would be a little slower anyway, its the only one that seems a little slow and always has been, had timers set at 14 for the front when new , but notice not all of the time did the bow bag get full, at 15 most of the time it does , this weekend was the first it didn't and was filling while putting back to the dock, will probably just go with adding the pumps if a ballast upgrade happens. Was just a curious thought, and thought I heard of others 17 and some 16s having higher fill times. Thanks for all your input Matt

This is interesting, as my dealer specifically advised never to run on both, always choose 1 or 2.

Edit: My bags seem to fill fine at the preset times. I always fill with boat on, idling forward.
