Northern Tool Company claims that the newer 208cc engines are "direct replacements" for worn out 6.5 HP engines. They list this under "historical data".

CC's of an engine refer to displacement. That has nothing to do with horsepower. Compressions ratios and other factors can cause large variations in horsepower for similar sized engines.
There is no direct correlation between displacement and horsepower. Just as an example, a standard 350 cubic inch Chevy engine can be built to produce anywhere from 150 horsepower to more than 1500. You would need to know the application, and how it was built, year model, etc.
There is no definite answer to this questions, but in general, you'd be looking at 5-6hp
Six hp, according to the conversion tables.
Six hp, according to the conversion tables.
That would depend on the year and what engine it has
The cubic centimeter displacement of an engine does not determine its horsepower.
CC is NOT correlated to Horsepower. Cc is merely the capacity of that engine, NO relationship to horsepower.
The volume of an engine does not necessarily determine its horsepower. That being said, the average 350 cubic centimeter engine is about 40 horsepower.
315 horsepower
11 kW = about 14.75 horsepower.
13.93 horsepower for 209 cc engine
