100/1
Actually, it is 50/1. I have a '99 with the original owner's manual and it clearly states that after the break-in period (which is 25:1) it is necessary to use 50:1. No older motor would be different.
As far as I know, only Yamaha o/b's use 100:1
I own an Evinrude 8 hp 1986 and the recommended mixture is 100:1 but I always use 50 to 60:1 and so far no problem.
Not only Yamaha my friend use 100:1 you should check your reference.

It has been suggested in recent years, a mixture of 100:1, I have always relied on the old tried and true, 50:1 ratio. One pint of 2 cycle oil, to six gallons of fuel, (50:1), has been used successfully for years, and I can honestly say that I have never seen an engine failure due to running this ratio.
