Ballast Fill/Drain Times

Recommended Posts

05hammerhead

Any chance people can chime in with ballast fill/drain times for your given year/model?  Ive been hearing a lot of people talking about their fill times and its making me worry as I ride often in the AM and lunch hours.  Are people modifying their ballasts?  Double pumping?  Reversibles?  I was just on the boarding schools Xstar and it could fill or empty in 3 mins.  Im assuming its using monster reversibles.

I disconnected my PNP bags and put them on dedicated reversibles. They fill in about the same time as the hard tanks now. Either way yeah you’re waiting for a lot longer than 3 minutes. Now it’s more like 6-7 minutes.

I guess Im looking for a how long was it before you "fixed" it and how exactly you did it.  Im assuming you just tied the the power off the aerators to a relay on the new reversibles?  Does that mean that you are always filling the PNP? Or do you have seperate switches for the PNP vs the hard tanks?  I was really hoping to get away from the separate switches.

A brand new aerator style 800gph pump will fill a 550lb sac by itself in about 6 minutes.  That slows down in my experience as the pump ages.  The rear hard tanks on my boat are about 225lbs each and took about 3 minutes to fill when the boat was new.  When I had PNP setup, I could add another 1-2 minutes on top of the sum of these just because of the resistance of pushing water into filling bags slowed down the flow rate.  All in all it broke 10 minutes.  I didn't mind the fill time so much honestly because I'm idling away from the dock and the first rider is messing around getting ready.  The front and center ballast would be full and I could still get up to a cruise speed to go where I needed to while the rear filled.  The drain time would be an irritation though.  It was just as long, and you absolutely couldn't plan on getting up on plane gracefully after a few minutes because you had no bow and center ballast and the rear was mostly full.  So you sat around for 10 minutes waiting to empty out before getting going on your way home.  Sometimes I'd remember to start draining the rear first while we packed up.  Then when I noticed the % actually start to go down on the tanks I'd start the rest of the boat and I could get up on plain with a balanced ballast gracefully.  Then it was only a 6 minute stall until we got going, instead of over 10.  Enough throttle overcomes all that of course, but I felt like a wally doing it.

So with dedicated pumps I set everything draining at the same time and they all drain at a similar rate so I can get going whenever I feel like it without feeling like I'm in a music video for Bootylicious during the hole shot.

Here's my thread on what I did with pumps and switches.

Thanks for that.  I guess Im in a unique situation as I work 4 mins from home and can ride over lunch.  20 mins of filling and emptying though wouldnt leave much for both my driver and I to ride.  I could leave the boat loaded on the lift I suppose, but that cant be good for the hull.

In my experience on the 23 LSV, my ballast is full by the time the engine is warmed up so fill time was never an issue.
