I have a 2008 250 E-TechHO model# E250DHLSC bought with my 2008 Rangerz21. Recently i have had the computer on the engine fail accordiong to the dealer. They have ordered a new computer. They also state that there are two injectors that may be bad. Is this common on the engine it has less than 170 hrs on it. Can anyone advise what causes this failure? Also does evinrude have any recall on the computers? Thank you for your advise and help.
