Sep 27, 2008

-   my 225hp envirude works perfectly at low rpm's or high rpm', but accelerating between 2500 and 3000 rpm's the engine chokes/vibrates/misfires and the engine light comes on ,the alarm also goes off, if i turn the engine off the alarm and engine light turns off but if try to go fast again the problem happens again(somentimes if i accelerate all the way im able to skipp the misfire and the engine respons fine), now it only occours in the water/ outside the water i can play with the trottle up and down all i want/with the prop engaged and nothing happens?? any suggestions-   zohany
