Serial #0G939607
Test was done on warm motor with all plugs removed and throttle wide open.
Port:
115
115
111
Starboard:
118
122
119
Can anyone give me an idea why the port side cylinders are lower than the starboard? The port side head is cooler to the touch when running on muffs but I’ve read this is normal. Any ideas? And should I be concerned about the 111 as Mercury states the specs for this motor are 110 - 130? I tested the port side first so battery charge would not be the cause.
