I purchased a used Ranger with a 1997 Johnson Faststrike from a dealer a couple of weeks ago. I have a 30 day waranty that ends in a week or so. My question is I have taken the boat out on numerous occasions in the last couple of weeks on one day check engine light went on when getting up on plane. I shut it down and waited a few minutes and all was well after and has been good the few times out since. Should this be somthing that I should have checked out before the 30 days are up?
