You can take the side cushion off to get to the nuts on the bottom of the tower, they don't usually make any noise there should be rubber between the tower and the boat and nylon wasers on the joints. All towers are going to move side to side even the 23' v-drive wake setters move side to side when you get into choppy water.
Everyone I've talked to - including friends with wakeboard boats and everyone at the boat show in Dallas last weekend (Supra, Mastercraft, Malibu included) - They all say the towers should not shake if they are properly reinforced.![]()
My guess is those were probably salesman. If its a lack of reinforcement then the hull would flex and you would have spiders in the gelcoat. If its squeaking or creeking its a sign somthings not tightend completly. Check every bolt and nut over closely. Then check them again. Locktite and locknuts on everthing!
Mine moves side to side about 1" to 2" when I get in choppy water but I have speakers,light rack, and 3 to 4 boards on my tower. I've never heard it make any nosie but the rubber spacer is sticking out a little bit.
im not sure what kind of racks you have ( or they use but the rubber in mine ar cracked and cut too. must be common but i think that board are hard on them also. im not to upset about it i got a good deal on them on ebay.
