1992 Evinrude flywheel

Is this 1992 Evinrude 115 flywheel missing something? or is this spot supposed to be open. Motor seems to be down on power at wot and noticed this when I replaced the rectifier / regulator. Thanks

Looks normal.----Start the trouble shooting with a compression test.----Then look for good spark on all leads.----And good spark will jump a gap of 7/16" or more.---Report what you find.

Compression is 106,107 passenger side and 119 and 120 drivers. To low of compression? I used a timing light and saw weak or no spark on the two bottom cylinders so I replaced the CDI module.It was better but after warming up started to lose spark.I noticed that the tach would work and then stop so I replaced the rectifier regulator and now the tach works and have spark at all cylinders.I changed the fuel / water filter and ran another gas tank to see if there was a difference before I replaced the rectifier and there was none. squeezed the primer bulb and there was no change as well. Checked the spark plugs and they looked good, gap was .035 so I replaced them and haven't been able to test. but it seems to not have power like before. The rpm's dropped 300 by adding 1 person at wot. Will do the spark test tonight. Thanks

Was finally able to check the spark and all leads looked to be at least 7/16. wonder if I should rebuild the carbs or is the compression to low on two of the cylinders.

Could be just a head gasket on the low cylinder's side (Passenger's side I assume is port side?)

Pull the cylinder head or the wee bypass covers to look at pistons and rings where you have 106 psi comression .
