Mercury115 Inline-6 gremlins

Gillie, whenever my 115 V-4 wouldn't idle real well, one or more idle jets were plugged. Don't know what sort of carbs your I-6 has, but the V-4 has two 2bbl carbs that have brass plugs covering both the idle and high speed jets on both sides. All I had to do was pull the access plugs to spot the plugged jet, pull it, and clean it. No need to pull or disassemble the carbs. Typically was about a 10 minute fix.

You can prevent by always running the carbs dry after use, but I don't like running 2 strokes out of oil. In fact, I when I wasn't going to use the boat for more than a week or so, when flushing it I used to rev it up to about 1000 rpm and then kill it with choke to dump a bunch more oil in it. Not as good as fogging it, but maybe better than a normal shutdown. After I started using Stabil or equivalent, that seemed to reduce the frequency of clogged jets. However I never ran much ethanol gas thru that motor. I know it can raise hell with all the internal fuel lines downstream of the filter, so might need to change them if they aren't rated for ethanol fuel. Denny
