I have a Rinker 232 Cuddy with a 350 MAG MPI. Recently, while using the boat the Tach began jumping all over and the boat would randomly lose power when under power. If I brought the throttle back quick enough the boat would stay running. If I didn't it would die but start right back up. It was fairly consistent every few minutes or so. I just purchased the boat and this was the third time I have had it out. Problem did not exist in first two outings. Any ideas? I wondering if it could be related to a failing ignition coil.
Thanks in advance!
