Howdy, fellow merc guys,, I have been fighting a cold start issue with the 115 in our pontoon for the longest time. The boat was in inside storage for bout 6 years due to health issues and am trying to get in top shape so we can get a smaller boat. I have been fixing some issues that developed due to it setting and have got to this ghost ignition issue of spark-no spark. To maybe clear up some things,, this is a 1983 model 115 in line 6 cyl, SN 6300368. I had to remove the flywheel to replace the "torsion spring" on the idle return, and after that, is when I started to get this ghost miss/no miss issue. since the crankshaft has the "notch" in the splines, the flywheel will only go on one way, so don't think the timing is the issue. After re-assembling everything, the engine was very hard to start and progressed to "no start". I checked the spark plugs and all seemed like new so went ahead and check them while cranking the engine. #'s 1 and 6 had great spark, but #'s 2, 3, 4, and 5 had very little or no spark! I downloaded some test info for stator and trigger from 3 sites on the internet but have some concerns as to what I am seeing on the testing of the trigger. According to test procedures for the stator,the results I get indicate it is OK. The trigger testing is another matter, tho. Here is my concern,,,,one publisher lists from Brn lead (W/O blk sleeve) to Wht lead (W/yellow sleeve) should be 11-14 OHMs. I get 1.236 OHMs @ 200 scale with my new Bosch Professional AND same result (1.236) with my Fluke 25 that has auto ranging. The other two publishers list recommended OHMs to be 800-1400 OHMs,!! In my feeble thinking, these are not all the same values, because whether actual meter reading is 1.2 on one scale, or 1.23 on next higher scale, , or 1.236 on next higher scale,,,,it is STILL only 1 (one) OHM,,right? I downloaded the online manual form here (twice) but do not find the testing procedure from Mercury. Can somebody please help on this????
