Alumacraft Navigator Sport 175 2004 vs Alumacraft Tournament Pro 170 2001 — Same Brand, Different Boat

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.

The Alumacraft Navigator Sport 175 2004 carries a rated maximum of 140 hp. 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.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Alumacraft Navigator Sport 175 2004 and Alumacraft Tournament Pro 170 2001 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Alumacraft Navigator Sport 175 2004 vs Alumacraft Tournament Pro 170 2001 — Common Questions

Which is easier to trailer — the Alumacraft Navigator Sport 175 2004 or the Alumacraft Tournament Pro 170 2001?
For trailering, the Alumacraft Tournament Pro 170 2001 has the edge at 1 005 lbs dry weight versus 1 245 lbs for the Alumacraft Navigator Sport 175 2004. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
What is the maximum horsepower rating for these boats?
The Alumacraft Navigator Sport 175 2004 has a documented max rating of 140 hp. Engine specifications for the Alumacraft Tournament Pro 170 2001 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Alumacraft Navigator Sport 175 2004 is Coast Guard rated for 5 passengers, while the Alumacraft Tournament Pro 170 2001 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

The Alumacraft Navigator Sport 175 2004 measures 93" wide, compared to 81" for the Alumacraft Tournament Pro 170 2001. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Alumacraft Navigator Sport 175 2004 or the Alumacraft Tournament Pro 170 2001?
The Alumacraft Tournament Pro 170 2001 has the bigger tank at 22 gallons, versus 4 gallons on the Alumacraft Navigator Sport 175 2004. That 18-gallon difference translates to roughly 54–90 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumacraft Navigator Sport 175 2004 and Alumacraft Tournament Pro 170 2001 from the same manufacturer?
Yes — both the Alumacraft Navigator Sport 175 2004 and the Alumacraft Tournament Pro 170 2001 are built by Alumacraft.
