Anyone have some advice on which motor I should look at to repower my 20' dual console fishing boat. The boat currently has dual johnson 50hp 2 strokes, but seeems underpowered. These motors are loud, polluting, unreliable, and unefficient. So I would like to improve in all categories, especially reliablity.<br /><br />What should I get. I know I want to go with a single outboard. Probably will get slightly used to save some cash. An Etec would be nice, but probably out of my price range. I have been looking at the yamaha 4 strokes. Hows the reliability and longetivity? How about the newer yamaha 2 strokes?<br /><br />What about the used outboards iboats sells? From guide services about a year or two old? Are they a good deal?<br /><br />thanks
