Me n my husband and son took out 100 HP Johnson motor boat out today and we were cruising full speed! Good time sun shining the wind was rough and beating is uo and giving the boat a beating. However that's nothing unusual. Suddenly we heard a difference in the motor and it slowly but surely grew weaker and died. What is this about? Does anyone know of this issue or has ever heard? Some feed back it any fee back will help! Thanks so much
