This motor is pushing a 25 ft. CC Pro Line and when after getting on 'plane' the motor will bog down. If I have someone continuously pump the bulb on the fuel line the motor runs OK. Motor seems to idle and run and slow RPM fine. Motor has been serviced by mechanic a year and a half ago with very little running time since. Could this be bad bulb? bad fuel pump? or maybe need new fuel/water filter? Any help would be greatly appreciated. Thanks.
