Need feedback from a Yamaha guru. I plan to replace my '84 200hp Yamaha with a new unit and have been quoted prices. I can get a 225 ox6 or a 200 hpdi for relatively the same price. Is there pro/con opinions on ox6 opposed to hpdi and 225 to 200hp? My old 24' Aquasport has performed great with the old 200 so I think either would do the job, I just need some opinions.
