Steve: Respectful stated: you can't make a displacement non-planning hull go much faster than hull speed no matter how much horsepower you throw on the transom. I've motored Sages and Montgomerys against current often and successfully and most times with a Honda 2/2.3 (excluding my M17 that.wad powered with a Suzuki 4). Yes slow going but going against adverse currents up to 4 knots. Watch first two minutes of this video - https://youtu.be/yc0ELdF7Zxs Horsepower can help _somewhat_ against wind as here what is slowing you is windage (hull, cabin top, and standing rig) and waves. I'll add it is generally unsafe to go against or with current flowing close to hull speed. :: Dave Scobie :: M6'8" #650 :: Baba 30 #233 DEJA VU :: SV SWALLOW - sv-swallow.com :: former owner M17 #375 SWEET PEA - m17-375.com :: former owner M15 #288 SCRED - m15namedscred.wordpress.com <<-- new site!

Dave, Have you ever sailed on the Columbia River? I have. There are times when my M-15 needs to go against the current, like every time I return. When there is no wind, more than 2hp motor is needed, something more like 4hp. The alternative is to let the river current carry the M-15 out to sea. Steve M-15 #335

I'm not aware of any outboard that is of appropriate size for an M15 that has an alternator. Alternators usually found as option for motors 5HP or greater. Some 4HP motors have identical powerhead (aka block) as a 5 and 6 HP so an alternator can be added by the owner.
Also, the alternator doesn't start putting out any significant power until the motor is turning higher RPMs ... meaning the M15 is being overpowered (trying to climb the bow wave and dragging the transom deep in the water.
A M15 has absolutely no need for a motor greater than a Honda 2/2.3hp. larger motors are bad for boat trim, aka sailing ability, because of excessive weight hanging aft of the transom.
