Detailed Evaluation & Buyer Recommendation

Pro Line 251 Wa 1997 vs Pro-Line 20 Bay 2011 — Same Brand, Different Boat

The Pro Line 251 Wa 1997 vs Pro-Line 20 Bay 2011 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 20 Bay 2011 tops out at 150 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 4 gallons in the Pro-Line 20 Bay 2011. 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 251 Wa 1997 is rated for 7 passengers, while the Pro-Line 20 Bay 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pro Line 251 Wa 1997 could be the deciding factor.

Bottom line: Choose the Pro Line 251 Wa 1997 if your priority is putting more people on the water — it handles 7 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Pro-Line 20 Bay 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
