Has anyone come across the advance timing screw on a 75 HP Mercury ELPTO being sealed with red wax?
I want to set the advance timing on my 1995 Mecury 75HP ELPTO. I have the official Mercury manual and it has pretty straight forward instructions for setting it to 20 degrees BTDC (cranking speed). My problem is that when I hook up the timing light and check the advance timing (before I have changed anything) it is showing about 28 degrees BTDC BUT the screw for setting the timing has been sealed with red sealing wax!
Has anyone come across this before? I do not want to be running my motor with the timing 8 degrees too far advanced but I also am reluctant to mess with something that has been sealed for some reason before I know why.
