Estimates based on research:

Merc Opti 200 hp ....
Best features - likely best fuel economy, range 200 miles +, over 50 mph WOT.
Drawback - well over 500 lbs, maybe heavy for V

Evinrude 200 hp
Best features - likely very good fuel economy, range 200 +, high 40's WOT,
Weight is reasonable 415 lbs.
Drawback - not quite as powerful.

Evinrude 200 HO
Similar to Opti, maybe not quite as fuel efficient at cruising speeds.
