gas octane

[94vette]

Hello,

I have a 1997 Tigershark Daytona 770. I have read the oweners manual and it sais I should run 87 octane rating. I have been running 91 octane, can you tell me if running 91 octane will cut down on the performance of my boat?


Thanks, Richard

It may a *little* - but most people on most skis will never notice.
