Alumacraft 1648 2007 vs Alumacraft Navigator 175 CS 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Alumacraft 1648 2007 or the Alumacraft Navigator 175 CS 2004?

For trailering, the Alumacraft 1648 2007 has the edge at 285 lbs dry weight versus 1 245 lbs for the Alumacraft Navigator 175 CS 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.

Q: Which boat can handle a bigger outboard?

The Alumacraft Navigator 175 CS 2004 is rated to a maximum of 140 hp, giving it the larger power ceiling. The Alumacraft 1648 2007 tops out at 35 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Alumacraft 1648 2007 is Coast Guard rated for 5 passengers, while the Alumacraft Navigator 175 CS 2004 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.

Q: Which boat is wider, and does it affect trailering?

The Alumacraft Navigator 175 CS 2004 measures 93" wide, compared to 7" for the Alumacraft 1648 2007. 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.

Q: Are the Alumacraft 1648 2007 and Alumacraft Navigator 175 CS 2004 from the same manufacturer?

Yes — both the Alumacraft 1648 2007 and the Alumacraft Navigator 175 CS 2004 are built by Alumacraft. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Alumacraft 1648 2007 vs Alumacraft Navigator 175 CS 2004 — Same Brand, Different Boat

The Alumacraft 1648 2007 vs Alumacraft Navigator 175 CS 2004 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 power gap is worth calling out. Rated to 140 hp, the Alumacraft Navigator 175 CS 2004 has a 105-hp advantage over the Alumacraft 1648 2007's 35-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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: Performance buyers should lean toward the Alumacraft Navigator 175 CS 2004 and its 140-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Alumacraft 1648 2007 with its 35-hp rating is the more economical daily driver.
