I've got an (I think) 1988 Mercury 115. Also have another one that's slightly newer (not sure the year--at least '89). The '88 is a 6-cyl, the newer one is a 4-cyl. Both are CDI. Ordered a new stator but got sent a trigger for some reason. New stator will take a week to arrive. Annoying. Upon...
Hi @50sman, did you get this issue resolved? I am having the same one. Struggling to get my mind around it, as I need to adjust both timing/synchronization and carb idle settings at the same time. Recently bought the motor used and cleaned the carbs, replaced trigger and CDI switch boxes. Dies...

I just bought an old mercury 115HP straight 4 cylinder (2 stroke). It's been sitting for awhile so I need some basics to refresh it. Trouble is, the serial number tag on the transom mounting bracket doesn't seem to have a number printed on it, though the tag does look original. Very strange...
New poster, new boat owner. Decent mechanical knowledge, but no expert on 2 strokes by a long shot and new to outboards in general. Bought the manual, trying to diagnose:
Bought the boat 3 months ago. Very little use by the last two owners over the past 20 years or so. No knowledge of use...
