I have a '72 Mercury 85 hp outboard. serial # 3496748.Can anyone send me a picure of the timing marks for this motor and any info i need to set the timing? i had to replace the timing belt and there are no visible marks that i can see. i haven't tried to adjust anything yet i wanted to see if i could get some help first. thanx
I haven't see your motor but if it is any thing like my 75 402 it will have 2 marks one for Idle timing that has 2 circles that line up from a timing light and 1 straight line for the WOT mark. I suggest you buy a manual for your motor though as the procedure can get a little tricky.
