Spawnout,

I just bought a 25 hp 4 atroke yamaha for my 14 ft Lowe. You definetely want to go with the 25hp if you can spare the change. My engine runs about 26-27 mph with two 200+ pound men, 2 batteries, trolling motor, full tank of gas and the rest of our gear. By myself, It hits 30+. Your gonna love the Yamaha.

Bene
