You do sometimes. A friend's brother-in-law worked on a variable-pitch
system for an outboard. The customer was apparently military - landing
boats. They wanted the absolute most out of their motors in all
conditions. And cost wasn't an issue.
Sydney's Manly ferry's use variable-pitch props, one at each end. But
they are a 1140 ton 70m long commuter ferry.
