115 four, problem

[Skipper 1]

I have a similar problem as romanchick, Motor runs fine up to 4500 rpms then starts cutting out if I give it full gas, acting like its starved for gas. I changed the fuel filters. Still have the same problem?

My 115 2-stroke is doing the same. Is yours carburated or fuel injected?

Check/ monitor the fuel pressures would be my first thought to see if there is a problem with the supply

mine is fuel injected. checked the fuel system. changed filters . I have no way of knowing what the pressure should be? maybe the pump is going out, I dont know?
