hello everyone,
So i picked up a couple old mercury 9.8's the other day from C'sL for next to nothing. both are in great cosmetic condition and have perfect and near perfect compression. one is a 69 and has a pretty simple ignition system the other is a 71 and has an ignition system i'm not super familiar with so i'm hoping there's an old Merc wizard out there somewhere who can point me in the right direction. the guy i got 'em from told me neither had any spark. checked out the 71 and one of the coils is obviously bad (terminal for - wire pulled out of the coil) but after some cranking i managed to get some intermitent spark out of the other cylinder. i'm out of town right now til thursday but wanted to get a few things to test when i get back. so far from my research i'm going to pull the flywheel and check the insulator blocks because i hear they are pretty common culprits for spark trouble in these motors. what i really want is to find a way to test the stator as it is by far the most expensive part of this system.
any suggestions, tips or ideas would be greatly apreciated.
