Engine size when using twins

Just curious why most twin engine displacement trawlers have engines that are the same hp as would be used if the boat had a single screw?

For example my 36 fd trawler has two 62 hp engines. Since 62 hp is more than enough power to cruise at hull speed wouldn't it be more efficient to have two 31 hp engines and still be able to cruise at hull speed?
