Hi. I need info. on what type of motor would best meet my wishes. I'm going to buy a used 24'-26'walk-around/hardtop. I'll be fishing in the great lakes and ocean so I'd like a motor that Ican use for long runs and trolling. I'm leaning toward a 4-stroke outboard. My main concern is fuel economy especially while trolling. I have the choice of IO with or without kicker, single or double 4-sroke with/without kicker or 2-stroke with/without kicker. Is their one engine out their that can do it all i.e., power for offshore runs and fuel sipping trolling? thanks
