When I throttle back and the throttle back up, my 2007 ETec 115 will intermittently not go above 3000 rpm. I brought it in and the mechanic changed 2 of the 4 injectors. It briefly ran properly (maybe 2 hours of running over the course of a couple days) and then started doing the same thing.
My boat is a 1997 model Neptune. I’m wondering if there could be a fuel delivery problem? Something in the gas tank ?
