    Default Bag fill timing question( I am overfilling)

    2018 SA, factory ballast.

    Fill time settings:
    7:30 fill time for rears and 9:00 center

    I started noticing I start spilling water out of ballast vents earlier and earlier.

    My assumption is my drain time needs to be increased and each time I drain, I am leaving more and more water in the ballast tanks, therefore my fill times are off more each time.

    Even with the bag overflows running, I pushed one of the rear engine dividers out of place. It popped right back in, but it tells me I am way overfilling the bags.

    I pulled boat out of water and noticed I could drain an additional 60 seconds worth of water before the pumps started spitting air.

    Is adding an additional 60 seconds on the drain timer the right approach?

    Mine was doing this in my 2018 SL. I have a theory.

    Do you drain/fill your ballast and use your boat a lot? I think as the ballast pump impellers get worn out, the filling is fine, but the draining is not as efficient. Maybe it has to do with the force it takes to push water out below the boat vs the water pushing itself in.

    The owner's manual says 100 hours and replace the ballast impellers. I'd have to agree with that. Mine were rock solid accurate based on timers until i got to about 80 hours. Then it started not wanting to drain that well.

    Only at 53 hours but still I agree fill is faster than draining.

    I will say this year I started filling while moving which could explain more pump voltage and thus overfilling.

    I tend to drain while idling, getting rider in boat, grabbing a beer, putting boards in rack, wrapping the ropes up etc.

    Do that 4-5times and I could have 300-500# water left in hard tanks.....fill next time would only finish filling faster.

    I will plan on replacing impellers this offseason as I will be nearing 100 hours at that point.

    Larry, I figured out mine weren't empty all the way for whatever reason as well. There is a setting in the menu where you can put the ballast reading at 100 full for whichever side or front. I did this after it started venting out. My next trip out, they were back to being pretty accurate. Maybe that helps some.

    Knox,

    Thanks man. I will find that screen.

    Fill each side one at a time to just start venting overflow and set to 100, repeat other side and front.

    Then empty all......

    Pull boat out of water and hit all 3 to drain until they start spitting air. Then take that time and add to the drain timer.

    Hit your menu screen, bottom left, then ballast settings screen...you can also verify everything is empty on the ramp and reset to 0. This is where the new ballast sensors come in. We have to do it manually, the sensors do this function for you when they start to overflow.
