Running the motor on a 20 ft pontoon runs smooth then a sudden jerk like hitting a log. then runs smooth for three minutes or so and jerks again sometimes will do it at slow speeds but not often and sometimes will not do it at all. cant figure out if motor is missing or if its in the lower unit. any ideas would be a great help. Trimming the motor has no effect as far as this intermittent
jerking thats driving me nuts.
