Never heard of Sinto Racing stuff.

There are proven products that will boost your octane, but they are not cheap.

Boostane, Torco or just blend with high octane race fuel or AV fuel.

"FOND DU LAC, Wis., Oct 8, 2008 – Mercury Racing (http://www.mercuryracing.com) is pleased to announce the fuel requirements for the 600 SCi sterndrive engine package have changed from 91 posted octane (R + M)/2 (98 RON), to a new minimum posted octane requirement of 87 (R+M)/2, (91 RON). The change affects both current and late model 600 SCi sterndrive engine packages. Mercury Racing engineering made the fuel requirement change after reviewing over two years of engine run data which validates that the difference in fuel grade does not adversely affect engine life, power or performance. The only measurable change consumers will notice is a savings at the pump."

I had 600's and if they came anywhere near anything less than 93 fuel the smartcraft would go into guardian mode.
