Pro Line 3400 SS 1999 vs Pro-Line 23 Sport 2006 - Boat Spec Comparison

Q: Which is the larger boat — the Pro Line 3400 SS 1999 or the Pro-Line 23 Sport 2006?

The Pro Line 3400 SS 1999 is the longer of the two at 35,0 feet overall. The Pro-Line 23 Sport 2006 comes in at 23,0 feet, making it roughly 12,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Pro Line 3400 SS 1999 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Pro-Line 23 Sport 2006 tops out at 225 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 Pro Line 3400 SS 1999 is Coast Guard rated for 10 passengers, while the Pro-Line 23 Sport 2006 is certified for 7. 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 has the larger fuel tank — the Pro Line 3400 SS 1999 or the Pro-Line 23 Sport 2006?

The Pro-Line 23 Sport 2006 has the bigger tank at 9 gallons, versus 3 gallons on the Pro Line 3400 SS 1999. That 6-gallon difference translates to roughly 18–30 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Pro Line 3400 SS 1999 and Pro-Line 23 Sport 2006 from the same manufacturer?

Yes — both the Pro Line 3400 SS 1999 and the Pro-Line 23 Sport 2006 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.

Detailed Evaluation & Buyer Recommendation

Pro Line 3400 SS 1999 vs Pro-Line 23 Sport 2006 — Same Brand, Different Boat

The Pro Line 3400 SS 1999 vs Pro-Line 23 Sport 2006 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 300 hp, the Pro Line 3400 SS 1999 has a 75-hp advantage over the Pro-Line 23 Sport 2006's 225-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 23 Sport 2006 carries 9 gallons versus 3 gallons in the Pro Line 3400 SS 1999. 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 3400 SS 1999 is rated for 10 passengers, while the Pro-Line 23 Sport 2006 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pro Line 3400 SS 1999 could be the deciding factor.

Bottom line: Choose the Pro Line 3400 SS 1999 if your priority is putting more people on the water — it handles 10 passengers and at 35,0 ft it has the deck room to back that rating up comfortably. The Pro-Line 23 Sport 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
