    Adding Sponsons?

    I am looking to add some low speed stability (the ski feels very "tippy" when I I ride two up, even my 6 year old daughter being on it with me makes it tough to control at low speeds) and sharper cornering to my 750SS. I see plenty of used ones on ebay that are off of similar ski's like the 750SS xi and 900 zxi complete with hardware so I'm thinking they will work quite well. My concern is where do I place them on the ski? If I'm lucky I might find a similar ski with factory installed ones at one of the local marinas that I can measure off of. Short of that what are my options? I did read some messages on here about the effects of moving it front to back or up and down from the stock location but nothing that gave me info on placement when there was no sponsons to begin with.

    Thanks.

    John

    I would go with the measure off another ski. I have the stx & zxi 900 both have different measurements and pitch. I am sure you would want placment to be exact on these!

    ZXI 900 sponson measure up 2.5 cm from the bottom edge this would be where all the bolt placements would be and measure in about 1 cm from the back corner this would be the placement for the back edge of the sponson.
