    Default New Ballast Reversible Setup...

    So I'm installing a completely new ballast system in my boat with 4 reversible pumps but I have a few questions.

    I have (2) 750's for the rears each will have their own pump, a center bag with the vent running to an IBS sharing a single pump, and a bag under the port seat with it's own pump..

    My question is vent locations, ie, best location to drill them and since we surf is it advisable to run the vents from the rear bags to the opposite side to avoid any draining issues from the boat being leaned over?

    Was thinking for the IBS vent towards the captains console since it'd be easier to access, where the heater is. The rears just on the middle area of the engine compartment.

    Save yourself some coin and link the port rear and the port mid ship together. Use a valve or simple plug like I made for when you don't want the mid ship bag filled.

    I suggest this as you aren't gaining any time with the fourth pump since you have the center & IBS chained together. I'm guessing your IBS is 650 and center is at least 400 for a total of 1,050. Your combo on the port side of 750 and I'm guessing the 370 totals 1,120. Thats only a 70 lb variance. In other words, it takes almost the same amount of time to fill center & IBS as it does port rear & mid ship.

    I'm venting my bags out same side in rear with no issues. Center & IBS combo where you suggested.

    That was my original plan, connecting the rear and mid ship together.

    Then my "buddy" wants to surf and he's goofy which messes everything up!

    I bought the forth pump so I could switch sides quickly and without hassle. I don't want to mess with anything except a switch. I wasted too many hours last year with tsunami pumps and opening hatches/moving stuff around, etc, etc...

    What I probably need is 2 valves for the 4th pump.

    So I could use the 4th pump to fill/drain the mid or rear(still have them connected) and another valve on the intake side to fill/drain from the lake or to the starboard side bag. (This is just too complicated, see note above)


    I'll use the 4th pump between the rear bags, and connect the port rear and mid bag together...

    Installed 4 reversible pumps and the thru hulls today.

    There is no space in this boat!

    Had to move the depth finder, was in the far left hole, now it's first in line..

    With the depth transducer moved forward, be prepared for some erroneous readings when the boats is at or above planning speed. The further forward it is, the greater chance there is for air to come across it. They do not "see" through are bubbles, so they tend to send incorrect readings. Same condition as when you key up with the boat on the trailer.

    Looks further forward than it is, only moved about 15 inches, figured the intakes would cause some cavitation and interfere with the depth sensor.. Guess we'll have to wait and see..

    On my 2008 LSV, venting the 1100 rear bags on opposite sides is needed for complete filling.
