Alumacraft Navigator Sport 175 2004 vs Alumacraft PF170 2007 — Same Brand, Different Boat

The Alumacraft Navigator Sport 175 2004 vs Alumacraft PF170 2007 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 Sport 175 2004 has a 80-hp advantage over the Alumacraft PF170 2007's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Navigator Sport 175 2004 is rated for 5 passengers, while the Alumacraft PF170 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Navigator Sport 175 2004 could be the deciding factor.

Bottom line: Choose the Alumacraft Navigator Sport 175 2004 if your priority is putting more people on the water — it handles 5 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Alumacraft PF170 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Alumacraft Navigator Sport 175 2004 vs Alumacraft PF170 2007 — Common Questions

Which is easier to trailer — the Alumacraft Navigator Sport 175 2004 or the Alumacraft PF170 2007?
For trailering, the Alumacraft PF170 2007 has the edge at 8 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.
Which boat can handle a bigger outboard?
The Alumacraft Navigator Sport 175 2004 is rated to a maximum of 140 hp, giving it the larger power ceiling. The Alumacraft PF170 2007 tops out at 60 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 Sport 175 2004 is Coast Guard rated for 5 passengers, while the Alumacraft PF170 2007 is certified for 4. 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 Sport 175 2004 measures 93" wide, compared to 74" for the Alumacraft PF170 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.
Are the Alumacraft Navigator Sport 175 2004 and Alumacraft PF170 2007 from the same manufacturer?
Yes — both the Alumacraft Navigator Sport 175 2004 and the Alumacraft PF170 2007 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.
