I have been using unleaded octane 87. I use Yamaha Ring Free and Yamaha Stabilizer in every tank. Guy at the Skeeter dealership told me to try Premium gas and I should see an increase in my speed. My boat is running about 5 mph slower than what it should.
Do any of yall use Midgrade or Premium in your boat? Do you notice a difference compared to unleaded? What are the benefits?
