Need to buy new engine for my Gheenoe. The candidates are Honda BF5, 1 cylinder, lighter and a couple hundred $ less than Yamaha and Yamaha F6, 2 cylinders.<br /><br />What are the pros and cons of 1 vs 2 cylinders? Will one idle smoother, be more reliable, easier to start (pull start)?<br /><br />Thanks for any advise/thoughts.
