Hi Guys! I have a 1997 Glastron GS 160 that I picked up last year (my fifth outboard boat). It has a 1997 Force 120hp (mercury marine version). A few minor issues. The motor seems to run well at WOT and starts right up cold or hot. The last time it was taken out however, it was run for about 4 hours at idle (trolling) and it quit. Plugs were fouled. Got a tow. I cleaned the plugs back at home and she fired right up. I was in the process of winterizing the engine today, ran it for 15 minutes in the barrel to get the stabil into the bowls on the carbs. I brought the RPMs up to 2500 a couple times during this process. I don't like spraying the fogger into the carbs while the boat is running. I usually pull the plugs, spray the fogger in the cylinders and turn the engine over by hand a bunch to spread the oil around. So, when I pulled the plugs after running the engine I noticed that all four plugs had a noticeable amount of oil on them, all four were wet with oil (and no I had not used the fogger yet) I have never had this on my other outboards, the plugs are usually colored up a bit and dry. My fuel mixture was 60:1, the engine did smoke quite a bit (it was cold outside). Compression is stellar 155, 154, 155, 155. Am I missing something? Does marine stabil 360 cause this? It seems to me that oil on the plugs would definitely lead to fouled plugs again if I was to run it all day. Any suggestions? Should I decarbon in the spring and lean out my fuelil mixture for a while? suggestions on synthetic oils to use for less blue smoke? Thanks in advance guys.
