Mate you should proberbly be looking at a v nose punt of some sort maybe quintrex explorer 385 (13ft) or similar for reasonable stability as the vee hull's in that size are a little unstable for moving around.The 6hp 4 stroke would push you around but maybe a 15hp would be better but also more expensive all the o/board manufacturer's make this size in four stroke and any of them would be a good little engine just get the best price.$6,000 maybe streching it a bit but do some shopping and see what you come up with then decide.Cheer's Dan...
