I'm planning to buy a 1448 Jon boat. I see that Alumacraft and G3 have boats in this size. The Alumacraft weighs 285 lbs. and the G3 233 lbs. I weigh about 185 and will be fishing alone. Both boats are rated for 25 maximum HP. I’m wondering how big a motor I should get. I don’t need a lot of speed but I do want to be able to get on a plane and move at a reasonable speed. I’m wondering if I should buy the Mercury 9.9 HP or 15 HP. I’d appreciate any opinions on this.
