This question involves the 1988 mercury 115 inline six in my previous post. Overall the motor runs strong, but i do have a few issues. When cold, the motor starts fine, idles fine, and turns around 5300 to 5500 rpm. Once it warms up, it has a tendency to bog while going to wot, and only turns around 4500. It does not cut out or miss at this rpm, it just never reaches full rpm. I've got good compression (129-135), fresh fuel and lines, gas mixed at 50:1. I pulled the plugs and none looked fouled to me, although i wasnt used to the flat style plugs in this motor. I know there was one switch box (in the last post i referred to it as a power pack) replaced and a new water pump put on. I just ordered a service manual from mercury for this motor, but was wondering if there was a way to test the stator, or switch box before i get the manual.
Btw, pumping the bulb does nothing to help the rpms jump, nor does choking it. Also, when it drops the upper rpm range, it no longer idles as smooth.
