I have a 1987 Bayliner 2150 bowrider with a 230 OMC stern drive. While accelerating under load, once 2500 RPM is achieved, the motor will begin to rev up and down by 400 RPM on each side of 2500 RPM violently before completely killing the motor. However, when placed into neutral the motor will maintain and achieve any RMP. The rate of acceleration does not affect the swing/kill when under load. Looking for any suggestions.
