I may be a bit late to this discussion but we've had really good luck with our Honda 2 horsepower outboard on our Montgomery 15 and it has had more than enough power in our experience except maybe once when motoring into a strong wind. We use the motor often on long trips and typically motor at low power settings. We get about 2 hours on the internal tank which I think is around a liter. We have an external tank, usually 3.5 gallons, that we pump with a outboard fuel hose with a bulb pump in it through a modified cap to fill the internal tank. This is a system I read about here. It works great even in rough seas. We secure the external tank in the back of the cockpit. We use the 3.5 gallon external tank each year we go to Lake Powell and, with some sailing in there, have covered I think over 150 miles lake some years on one 3.5 tank (we usually stop and add some but typically have ended with about what we put in).

The best fuel can setup is having one 1-gallon and a larger 2.5 gallon. The 1-gallon is used to fill the motor. As the one gallon empties transfer fuel from larger to smaller can. Use the No-Spill brand - https://nospill.com Having 3.5 gallons aboard gives you 14 hour range. Use gallons/hour as direction wind/current/waves will increase/decrease range = KPG (knots per gallon) isn't consistent for distance over ground. If you need more range have the large container be a 5-gallon. Store containers at the aft end of the cockpit.

A friend in Connecticut who was in the Coast Guard and sailed an M17 without an engine, had to go from his CG mooring to a ramp to put the M17 on a trailer. The ramp was was about a mile upstream on the Thames river. He asked me if he could use my 2 HP HONDA to make the move. I brought the engine to New London and we mounted it on the stern of his M17. He had brought the M17 from his CG mooring to the New London dock under sail, where, after mounting the HONDA, we took off under 2 HP HONDA power upstream; against outgoing tide; with four adults in the cockpit. The HONDA drove the M17 at about 3/4 throttle upstream very nicely against wind, tidal flow, and load with no problem. The 2 HP HONDA isn't enough power to plane the M15 or M17, and it can't tow a water skier, but it got us to the ramp very easily. Connie ex M15 #400
