Why are boat motors so expensive? For example a 10 hp motor costs about 1400-1600. A 5 hp 2 stroke costs about 700-800 or more. Don't even look at more hp that is out of range for a middle income guy that just wants to fish some. I can't see that these are so high tech that they should cost this much. Don't give me the baloney about research and development. They haven't changed that much. You can get car motors for less.
