    Impeller and Wear Ring

    2015 SeaDoo GTX iS Limited. The ski doesn't hook up like it used to. The ski gets lent out too much. See the attached file. Is that enough damage to the impeller and wear ring to impact acceleration very significantly?

    JPT, Is this what you mean by the pump shoe damage? The word "shoe" doesn't appear anywhere in the factory service manual. Could it be called something else

    The pump design in a Seadoo is ‘axial flow’. An ‘impeller’ with twisted vanes in a pipe with an intake and discharge area.

    ‘Shoe’, to describe the pump housing, is not an engineering term.

    Pump performance is a science and even what we may consider to be minor damage can have a great impact on performance.

    I learned the hard way: Swim your craft into a min of 4ft of water and idle forward until you have 10. No heavy throttle until you’re in deep water.

    Coming back in, kill the engine as soon as possible -you don’t want stones being pulled of the shallow floor and colliding with the innards of your propulsion system.

    Anyway, your impeller has some damage. That’s probably where the issue is. Hard to tell how badly the ‘pipe’ damage is affecting the performance but it may well be affecting fluid dynamics too.

    part 22 Pump support is commonly known as the pump shoe.

    In your photo, 10 o'clock there are numerous perferations in your pump shoe. Like I said somebody ate some rocks and caused all of this damage!

    Thanks JPT. That is helpful. I won't be doing the repair for about two weeks but I will post the results.

    I installed a Solas impeller and new wear ring I got from Greenhulk. It is a completely new ski. I has better hole shot than when it was brand new. Thanks Jerry.

    Glad your ski is better than new. Question: Did you do SS or OEM wear ring? also what pitch Solas?
