WAB, depends on the dinero and application. I just did this drill two months ago. I have owned carbed outboards but here is what I found. I live in California for the rules are a little different in reference to emissions. We need to comply with 2006 EPA regs.
Choices: OX-66 Yami, HPDI or 4-Stroke.
OX-66 bullet proof and well proven. I have heard from two sources they will not offer this motor in 2003. I can't buy a boat for Cali with a OX-66.
HPDI was my choice since it is still a 2-stroke (less moving parts) and meets the 2006 EPA standards (yeah!). Great motor now with 19 hours on it and runs great, no smoke, no stink, good on oil and gas.Also pops off and runs smooth on the slight key turn. Nice.
4-Stroke is a great motor, smooth torque band, quiet at idle, great fuel efficency. Cons, more moving parts, timing belts, changing the oil, heavier and bigger. More dinero $$ about $3K more.
Just my $.02. [img]/infopop/emoticons/icon_wink.gif[/img]
