Pro-Line 17 Sport 2008 vs Pro-Line 21 Sport 2005: Same Brand, Different Boat

The Pro-Line 17 Sport 2008 vs Pro-Line 21 Sport 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 power gap is worth calling out. Rated to 200 hp, the Pro-Line 21 Sport 2005 has a 85-hp advantage over the Pro-Line 17 Sport 2008's 115-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Pro-Line 21 Sport 2005 carries 70 gallons versus 40 gallons in the Pro-Line 17 Sport 2008. 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 Pro-Line 21 Sport 2005 is rated for 6 passengers, while the Pro-Line 17 Sport 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pro-Line 21 Sport 2005 could be the deciding factor.

Bottom line: Choose the Pro-Line 21 Sport 2005 if your priority is putting more people on the water - it handles 6 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Pro-Line 17 Sport 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Pro-Line 17 Sport 2008 vs Pro-Line 21 Sport 2005 - Common Questions

Which is easier to trailer - the Pro-Line 17 Sport 2008 or the Pro-Line 21 Sport 2005?
For trailering, the Pro-Line 17 Sport 2008 has the edge at 1 700 lbs dry weight versus 2 600 lbs for the Pro-Line 21 Sport 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.
Which boat can handle a bigger outboard?
The Pro-Line 21 Sport 2005 is rated to a maximum of 200 hp, giving it the larger power ceiling. The Pro-Line 17 Sport 2008 tops out at 115 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 Pro-Line 17 Sport 2008 is Coast Guard rated for 5 passengers, while the Pro-Line 21 Sport 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 Pro-Line 21 Sport 2005 measures 101" wide, compared to 92" for the Pro-Line 17 Sport 2008. 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 Pro-Line 17 Sport 2008 or the Pro-Line 21 Sport 2005?
The Pro-Line 21 Sport 2005 has the bigger tank at 70 gallons, versus 40 gallons on the Pro-Line 17 Sport 2008. That 30-gallon difference translates to roughly 90–150 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Pro-Line 17 Sport 2008 and Pro-Line 21 Sport 2005 from the same manufacturer?
Yes - both the Pro-Line 17 Sport 2008 and the Pro-Line 21 Sport 2005 are built by Pro-Line. 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.
