    Default Tower "Wiggle"

    Hi guys, new to the Moomba family with an '04 Mobius XLV I bought a few weeks ago. I feel like the tower wiggles a lot when going over rough waves/chop. I have read all I could find on here about checking the bolt tightness (but not too tight!), etc., so this is more a question for those other XLV owners out there as to how much wiggle is considered normal? Never had a boat with a tower before so I have no idea if this is totally fine or if I should be worried. Some smallish gelcoat cracks around each tower base as well (looked at those pages on this forum as well, sounds like a quasi-normal/minor thing?).

    Items on the tower:
    4 MB Quart chrome speakers (factory maybe?) - fairly large, maybe 6-8" in diameter and 8-10" deep
    Wakeboard racks on either side with 1 wakeboard in them
    Foldable bimini top
    Mako light bar

    I feel like that weight shouldn't be an issue given that we tow humans from it. Only tow surfing right now too, tubes and skiis go from the pylon.

    And to clarify too, I'm talking side-to-side movement, not front-to-back...

    I'm guessing this is pretty normal. Ours does the same thing.

    Yea, even my '06 does it, only gets worse the more speakers/weight you put up top. You gotta remember, these year boats are still 'ski' boats with a tower. It's an add on. Having 4 feet with very small contact points is gonna give it some wobble. Nature of the beast.

    Helps to hear this is normal. Previous owner took care of the basics but some of his mechanical skills have me wondering. Now I have the tendency to see problems everywhere!

    I have an 08 and have had many other types of boats over the years, they all flex. Just check the bolts regularly.
