I give Krenn Power Sports 5 stars (because it won't let me give him 10) Trust me when I say that not all shops have his ethics. Years ago I used another shop to diagnose & repair a power loss issue I had with my Sea Doo. Not only did they not fix the issue they told me it would probably need a whole new engine! After a substantial bill & two days later with little results, they did offer to sell my a BRAND NEW SKI! Fortunately I was referred to John Krenn, John is extremely knowledgeable, honest, gives great service & very reasonable. He get's it done right the first time! I called him, described the problem & he knew exactly to do, it was old fuel lines and a gummed up carb. Now the ski runs GREAT & it took less than a day. John is an excellent mechanic who is very happy to share his extensive knowledge of PWC mechanics. He has helped me fix my skis on many occasions the last 5 years, a few times right over the phone & once even on a holiday week end! Krenn Power Sports has my business for life!
