So I have a 2075GL with a Yamaha F75 4 stroke. I have the opertunity to purchase a Yamaha 115 Hp 4 stroke of the same year. I would go larger but the boat nameplate states max. motor of 115 hp. Will the extra 40 hp make a significant difference in speed and turning power? My boys have been wanting max speed of the 75 for several years while tubing.
