a likely source of your problem might be overheating. my evinrude has what they call slow mode. when you are hot it goes into slow mode till it cools down. in slow mode i could not plane out and the motor shook side to side. check your impeller and or water pump housing for damage. do not run dry.....will melt impeller.
To set the cable on a 40 hp Johnson boat motor, first ensure the motor is in neutral. Then, locate the throttle and shift cables; they typically have adjustment screws or nuts. Adjust the cable length by loosening the screws, sliding the cable to the desired length, and tightening the screws back in place. Finally, test the throttle and shift functions to ensure they operate smoothly without excessive slack.
to fix that problem with it cutting out let it warm up a little bit before like 30 40 seconds or so and then barrely pull in on the throttle and then just give it more throttle steadly and after that it should be ok
Wide open throttle (WOT) is a term used for any engine when the accelerator is held to the floor and the throttle plate(s) are wide open.
