Sorry for the long post.
I got the Ballast Puppy pump from Jasco and the same fill / empty switch used by Jeff Lind in his great post... Thanks Jeff ...
http://www.wakeworld.com/MB/Discus/messages/3183/105071.html ... but I've still got some questions for maybe Jeff or others who have done this project and Malibu DD owners.
Here' goes:
1. Where did you mount the rocker switch on your BU? I've got a few options:
a) on the blank spot on the dash. However it's a different type of switch and the fit is real tight. It's going to be a challenge.
b) on the right side of the driver on the panel that houses the circuit breakers. I'm afraid of having the vinyl pop out the side of the switch and it will look bad.
c) mount an angle bracket made from aluminum just below the dash on the right side of the driver and mount the switch sideways. It would be out of the way but still very usable. Not as clean if one of the others is done well.
2. Where did you mount your pump if you have a DD Malibu? I'm thinking of mounting it off the support bracket that runs off the block and around to the center cam shaft. That way it will up off the floor (and out of any bilge water) and won't be in the way.
3. How did you run your hoses? I want to run three lines up front (Left, Center, Right) and one main line to the rear where I will "T" it behind the back seat and run one hose to either side of the boat.
4. Do you keep your bags perminently attached to your system after filling? I usually run one bag in the walkway up front. I don't want to drill a hole in the glass for a hose, so I was going to put the hose under the cushion and just plug it in and out as needed with a valve on it. I think all others could be perminently attached and just rolled up and tucked away when empty except for the locker sack that I'll just leave in there perminently. Maybe I'll get some custom triangle bags for under the bow cushions. Don't know yet but I want to keep that option open.
5. Finally, do you have a main valve near the ballast puppy that you must turn when filling or after filling to keep the water from either pushing into the bags while underway and overfilling due to engine pressure, or getting sucked out while underway and loosing water in your bags due to engine suction?
Any and all input would be appreciated.
