Detailed Evaluation & Buyer Recommendation

Pro Line 251 Wa 1997 vs Pro-Line 31 Sport 2005 — Same Brand, Different Boat

The Pro Line 251 Wa 1997 vs Pro-Line 31 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 Pro-Line 31 Sport 2005 tops out at 600 hp. Engine specs for the Pro Line 251 Wa 1997 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Pro Line 251 Wa 1997 carries 138 gallons versus 3 gallons in the Pro-Line 31 Sport 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 Pro-Line 31 Sport 2005 is rated for 9 passengers, while the Pro Line 251 Wa 1997 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 31 Sport 2005 could be the deciding factor.

Bottom line: Choose the Pro-Line 31 Sport 2005 if your priority is putting more people on the water — it handles 9 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Pro Line 251 Wa 1997 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
