I understand how octane works, higher octane, higher combustion point. Less perignition, greater volume in cylinder for explosion= more power. I'm not sure how changing it now could cause a problem. The original PCM service manual and MasterCraft owners manual call for minimum 93 octane, which is hard to come by. The reason for considering is the afore mentioned slight hesitation when getting into the throttle to pull my 285 lbs out of the water, particularly in April and November in Wisconsin. As I mentioned it seems that several mechanics believe this, though since they can't say why I believe it is likely to be an old wives tale.
