The Alumacraft Navigator Sport 175 2004 vs Alumacraft Tournament Pro 170 2001 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Engine data for the Alumacraft Tournament Pro 170 2001 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Alumacraft Tournament Pro 170 2001 carries 22 gallons versus 4 gallons in the Alumacraft Navigator Sport 175 2004. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
