I'm looking for about a mid-90s 20 or 21 ft. bass boat. That means I'm looking at a 200 or 225 motor. To be honest, I don't know much at all about motors. What motors (brand and year(s)) are good ones and which ones should I seriously avoid? Is it enough, regardless of brand (Rude/Johnson, Merc, Yamaha) to just have the motor compression checked, or do I need to be very brand/model year cautious, regardless of any checks? Also, is there anything wrong with getting a motor that has been rebuilt? Remember...we are talking about motors that are approx. 15 years old. Thanks.
