The hook up and handling of this model ski is good in calm water but is left wanting in choppy to rough conditions. The WR531 Sponsons will go a long way to help get the power and performance out of these boats in all water conditions.
These sponsons will improve the turning and tracking of these boats to get the most out of their very powerful 4 stroke engine. The stock OEM sponsons only really help the back of the hull from settling to low in the water and do not come into play in turns, the Worx blade type sponson will hold the boat in the tightest turns and make it straight line track a lot better in choppy water and through boat wakes.

Note: Before purchasing, check below that your OEM sponson mounting bolts match the backing rail bolt layout pictured below.
