Re: sail outboards
Many are exact copies of old, EPA prohibited Yamaha designs. Which solves the parts & service problem. Origin is mainland China. I tried to track down the factory but didn't get too far. Some suspicions but nut much further.
The lack of complaining on Yamaha's part leads me to suspect they're actually being produced under license.
EDIT: Oh, but the 4 strokes are the same as new Yamahas. So that would suggest copying w/o a license. I wonder why Yamaha isn't complaining?
