I can't see running higher octane ever hurting an engine... I would also start adding seafoam to each tank - its something I do and have done for a very long time. I have engines that sit in Ontario Canada for 49 weeks a year...Always had hesitation in my outboards for the first week when refitting for fishing time...ever since seafoam - it's like the 49 weeks never happen.

I agree - you can avoid a carb rebuild - I could...when you do you can go twin supercharge? This setup would have no problem getting you out of the water...
