    I burn a very little bit of oil just due to the heavy load but it's the same wakeboarding vs. surfing. I'm not too concerned with the effect of the lean angle on the motors. It's extreme for boating...

    They should fit perfect. It has the same overall dimensions (50x24x24) as the 1100#. The volume difference is just due to the circular cross-section.

    So apparently 2007 is the year they changed. They are pretty handy but like bergermaister said it's really only once or twice a season. In any case I bet you could contact a SC dealer (I always hear...

    Are you talking about the quarter turn latches that hold the hinge panel in the "up" position? What kind of trouble are you having? Those work well for me.

    And by "needed" he means "the absolute max that will fit"!

    I think that you'll see a difference between your 800# sacks and 1100# but I don't think you'll see a huge difference between the 800 and...

    Ah, now that makes sense but the advantage would be cable size by sharing one shield, but it wouldn't improve noise immunity.

    But with a total investment <$100, I don't think I'd care even if it only lasted a few years. It would still be 1/10th the cost of seadeck

    They are playing off of the terminology of a twisted pair conductor, which is a good transmission line for a differential signal but are talking about the stranded wires of the coax shield? Twisting...

    Yes, a coax cable is the best choice for basically everything you'll find at home or in your car - anything with RCA connectors. And yes, I believe that "dual twist" is just a marketing word. Those...

    We just pulled the carpet out of the lockers. It just pulled right up. We did use a scrapper to get the little stuck on bits but it was pretty easy.

    Exactly.

    And it's worth pointing out that basically all amplifiers use differential op-amps so the manufacture may well state that they use differential amplifiers but in no way does this mean...

    That's true if the drivers/receivers are differential. If they are single ended (which the ZLD is) then a coax RCA is the right cable.

    Sure, but doesn't carpet trap all of this too? The benefit is that you could hose this stuff clean and it won't stain.

    MLA,

    Sorry, but I don't agree with you. The setup that jmvotto describes won't be slower. It may seem slow because you have to wait for the first sack to fill before the second one fills. Running...

    Here's a quick sketch:

    If the same pump is used in each case, containers A and B will fill in the same amount of time.

    In fact, container A would fill faster than B. Exactly the opposite...

    Nope. You're missing the key concept here. If the 1180 sack is 2' tall and the 250's are 1' tall (I assume they are side by side) and are stacked on top of the 1180. Then the pump performance will be...

    No, the head loss is due to the 3'3" vertical column of water not the hose. It doesn't matter how big the sack is, only how tall. The 1100# fat sack is 2' tall (24"x50" LxW) which when full, puts...
