1995 Mariner 225 (3.0L Carb.) model: I was heading back to the ramp and all the sudden the motor missed a little and shut down completely. I was able to start it after a few minutes and limp into the ramp, but the motor had no power. Felt like it was only running on a few cylinders. I had to idle a long way to get into and out of where I was fishing. I noticed on the way out it was missing a little every once and a while. I attributed it to the slow speed, but I thought it may be relevant. Otherwise I did a lot of running and it did great all day. I am mechanically inclined and if I could test and fix myself i would enjoy that, but really I want to have an idea of what is wrong before I take it to someone. Any help would be appreciated. Thanks!!
