Alumacraft Navigator 165CS 2001 vs Alumacraft Navigator 185 CS 2005 — Same Brand, Different Boat

The Alumacraft Navigator 165CS 2001 vs Alumacraft Navigator 185 CS 2005 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 185 CS 2005 tops out at 150 hp. Engine specs for the Alumacraft Navigator 165CS 2001 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Alumacraft Navigator 165CS 2001 carries 22 gallons versus 4 gallons in the Alumacraft Navigator 185 CS 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Navigator 185 CS 2005 is rated for 6 passengers, while the Alumacraft Navigator 165CS 2001 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 185 CS 2005 could be the deciding factor.

The Alumacraft Navigator 165CS 2001 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 165CS 2001 vs Alumacraft Navigator 185 CS 2005 — Common Questions

Which is easier to trailer — the Alumacraft Navigator 165CS 2001 or the Alumacraft Navigator 185 CS 2005?
For trailering, the Alumacraft Navigator 165CS 2001 has the edge at 88 lbs dry weight versus 1 351 lbs for the Alumacraft Navigator 185 CS 2005. 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 185 CS 2005 has a documented max rating of 150 hp. Engine specifications for the Alumacraft Navigator 165CS 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 165CS 2001 is Coast Guard rated for 5 passengers, while the Alumacraft Navigator 185 CS 2005 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 185 CS 2005 measures 96" wide, compared to 82" for the Alumacraft Navigator 165CS 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.

The Alumacraft Navigator 165CS 2001 has the bigger tank at 22 gallons, versus 4 gallons on the Alumacraft Navigator 185 CS 2005. That 18-gallon difference translates to roughly 54–90 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
