So I came across something strange when i was adjusting the advance timing on the ole Sea Ray (1984 Sea Ray 5.7 L OMC). At idle, it was at -5 degree, at 3000 RPM, it was showing about 10 degrees. So i adjusted the total advance at 3000 RPM to 32 degrees per spec. The boat used to run WOT at about 3700 RPM, but now at 32 degrees, it's hitting 4200 RPM. It sounds great. However, now when I check the timing at idle, it's showing like 20 degrees. It's supposed to be 8 degrees. Anyone have any ideas why? Should I be concerned? Thanks in advance.
