[Charlie B]

Displacement speed for a boat that size is about 6 mph. and a 15 hp. kicker will probably get you that speed in most if not all sea conditions without running at full throttle. The big plus would be the very slow trolling speed you would be able to get at a very low fuel burn. Think power drifting for fluke without bumping in and out of gear. Or trolling all day on very little fuel. An other benefit to think about is if the kicker has electric start and an alternator and if you have a dead battery you could start the kicker by hand to charge your battery enough to get the big motor started...Charlie
