Hello. I'm looking at buying a used 2013 Yamaha F-4 outboard. It's a 4 HP motor. It would replace my older Yamaha 6 HP motor. Do you think this is powerful enough to do the basic work I need? Things like in/out of slip, distance motoring when wind is dead, etc. Thanks very much for any advice you can give. Ed Connors/Chesapeake Bay.
