I'm in the market for a new outboard. I have my eyes on a 4HP 4 stroke Nissan or Tohatsu. Interested in hearing any comments or recommendations on either of these outboards for the Catalina 22. I sail on inland lakes and like the idea of an integral tank motor with F-N-R capability. Also, until now I have been using a 3.5hp Mercury (2 stroke)with a standard short shaft (15"). The length has not been an issue (15" is fine with my lowering motor mount), so I can stay with a short shaft unless recommended otherwise. Thanks in advance!
