Value of used outboards

Yes I am now looking at 150 HPDI. Lots of confusing information out there. It seems as though there may be more available mid range torque with the HPDI with comparable fuel burn at all but the lowest RPM ranges.
It is amazing that both of those engines weigh more than my current Yammy 200.
I am still looking for some acual dyno numbers for both engines just to verify what I have been reading about both engines.
It appears none of the mfg's want to provide that info.
