I just got this boat. It has sat for over 10 years. At first I didn't have a spark at all, so i went and got a used cdi box. I got spark now, but the motor only runs for about 5-10 min. then dies. It won't start and I can't get any spark.<br />PLEASE HELP<br />I have no clue about boat motors<br />thanks for the help!!!!
