5 HP is a good fit
The Mercury(by Tohatsu) 5 or 6 HP Sail Power with the optional alternator would be worth considering. Bought new in 2013 I have about 80 hrs on one. Always starts on second pull and uses about a third of a gallon an hour at 2/3rds throttle and yields around 4.5 kts.We did our taxes and although we have to pay state our federal is helping send my wife and daughter to Germany for 2 weeks so I will stick to the 4.5 hp for now
