Hey there, i need your insight as to what is most likely the problem with me outboard. it starts and runs fine at low end say trolling, but give it the stick she'll jump and run for about 20- 30 sec, and drop back to trolling. if I have someone prime the ball (pump it) the boat runs flat out on problems !!!! so gents it it a fuel pump /diaphragm, etc or ??? thank you .Larry

Repair the fuel pump or look for leaks in all the hoses.----------Also determine if you have proper pressure pulses to drive the fuel pump.
