In the market for a 225HP range outboard and choosing between a 2 and 4 stroke. I understand the 4 stroke is quieter, more fuel and oil efficient, and can be run at WOT without worry, but that it has less power in the mid and high end than a 2 stroke. I've also heard that Yamaha's HPDI (high pressure direct injection) technology is very good. Any thoughts/advice?<br /><br />Thanks.
