25 hp Timing question ..

[Danagc]

I have a 1988 25hp outboard motor. I was wondering if anyone is familiar with timing one of these ? Is it done at idle speed, what degree is it suppose to be set at ? It looks like theres a linkage adjustment below the flywheel to advance or retard the timing, but not positive thats what its for. Any advice ? I know, buy a manual. : ) thx Dan

Yes get a service manual the timming is not something you want guess at.
