I am looking for a 4-6 HP outboard for my boat. I noticed that the specifications for the Suzuki DF4, DF5 and DF6 are identical except for the power output and the rapidly increasing price. Presuming these are all the same basic engine, what is the difference that gives the extra power? The obvious next question is, could you buy a DF4 and alter it to get 6HP out of it?
