I have a twin seadoo speedster sk thats sick.
I've owned the boat since new and had no problems till 2 years ago.
One engine started to fluter at wot and drop from 7k rpms to 5500. If I drop it back to 6200 rms its fine.
I have taken back and forth to three dealers and spent $2k adn still....... no effects on performance. The first dealer replkaced an impelller and housing with little wear. The same dealer after I returned rebuilt the engine (piston & rings) because the copreion was down 15%....right! Still no change in performance ....sothird try at second dealer who procceded to rebuild carbs, replace fuel filters, and just because I'm a gluton for punishment... I had him do the other carb. (by the way I've done nothing else other than plugs to the second engine and it remains as strong as always.
Please some help!!!!!!!!!!!!!! I love my boat but cant find anyone able to diaognose its issue.
