Hi guys. I am struggling to find the right motor for a small Copperhead skiff that Mel will be building for me. I would love to buy an Etec, but they are not really available and may not be in my time frame. Yamaha is becoming a top choice and am I right here? You no longer have to pre-mix oil in with the gas? This is important to me since Mel is building in a 12 gallon tank. Anyone have experience with the Yamaha 2 strokes? Opinions ? How reliable is this oil injection system? Thanks!
