Timing is retarded about 40 degrees. New timing light confirms it with the remove sparkplug way. Too weak to do the 100 foot pound safety nut removal.

It is really a odd ball nut on the 1986 28 SPL and 30 hp motors flywheel. Crowley Marine parts sheets even shows what my motor has. I never saw a domed nut before.
