Alumacraft Navigator 165 CS 2004 vs Alumacraft Navigator 165 Sport 2012 — Same Brand, Different Boat

The Alumacraft Navigator 165 CS 2004 vs Alumacraft Navigator 165 Sport 2012 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.

Both boats share a closely matched power ceiling — 75 hp for the Alumacraft Navigator 165 CS 2004 and 90 hp for the Alumacraft Navigator 165 Sport 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 22 gal and 19 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Navigator 165 Sport 2012 is rated for 6 passengers, while the Alumacraft Navigator 165 CS 2004 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Navigator 165 Sport 2012 could be the deciding factor.

Bottom line: Choose the Alumacraft Navigator 165 Sport 2012 if your priority is putting more people on the water — it handles 6 passengers and at 16,7 ft it has the deck room to back that rating up comfortably. The Alumacraft Navigator 165 CS 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Alumacraft Navigator 165 CS 2004 vs Alumacraft Navigator 165 Sport 2012 — Common Questions

Which is easier to trailer — the Alumacraft Navigator 165 CS 2004 or the Alumacraft Navigator 165 Sport 2012?
For trailering, the Alumacraft Navigator 165 CS 2004 has the edge at 88 lbs dry weight versus 105 lbs for the Alumacraft Navigator 165 Sport 2012. 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.
Which boat can handle a bigger outboard?
The Alumacraft Navigator 165 Sport 2012 is rated to a maximum of 90 hp, giving it the larger power ceiling. The Alumacraft Navigator 165 CS 2004 tops out at 75 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.
How many people can each boat hold?
The Alumacraft Navigator 165 CS 2004 is Coast Guard rated for 5 passengers, while the Alumacraft Navigator 165 Sport 2012 is certified for 6. 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.
Which boat is wider, and does it affect trailering?
The Alumacraft Navigator 165 Sport 2012 measures 91" wide, compared to 82" for the Alumacraft Navigator 165 CS 2004. 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 165 CS 2004 or the Alumacraft Navigator 165 Sport 2012?
The Alumacraft Navigator 165 CS 2004 has the bigger tank at 22 gallons, versus 19 gallons on the Alumacraft Navigator 165 Sport 2012. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumacraft Navigator 165 CS 2004 and Alumacraft Navigator 165 Sport 2012 from the same manufacturer?
Yes — both the Alumacraft Navigator 165 CS 2004 and the Alumacraft Navigator 165 Sport 2012 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.
