V21 with mid 90's looper Evinrude was definitely adequate....even with 4 people on board and full fuel.   I had one......till decided to sell and rig the 200. 
 
 Rude dealer told me those loopers produced around 165 prop hp, so plenty of power.  Top speed was high 30's.  Some guys claim as fast as mid 40's with 150 on V20's........maybe down hill....:)
