Welcome to the seadoo forum 05gtxsc. No the only reason you would need to run a higher octane is if it was experiencing detonation. Then it would need more octane to keep it from doing that, which would put a hole in the top of the piston, if you didn't use the higher octane.
Please, If you have a "troubleshooting" request, use the correct category in the Sea-Doo Forum first.
