Ok would really appreciate any suggestions before I take this thing in to get it scanned! Boat was running fine then after shut down for a while to fish started back up and could not break 1900 rpm WOT almost like the old carbed 2 strokes loading up. But no lights or warning horns, strange!!! Put it on the trailer put the muffs on fired her up and was able to get full RPM but engine light came on once it hit 3500 RPMS but no warning horn. Have correct plugs/ gapped /cleaned / reinstalled problem still exist, TPS sensors were just replaced last year. Really stumped any help would greatly be appreciated.
