Bennington 165 Si 2004 vs Bennington 2250 RFS 2004 — Same Brand, Different Boat

The Bennington 165 Si 2004 vs Bennington 2250 RFS 2004 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.

Size is the most obvious dividing line here. The Bennington 2250 RFS 2004 measures 21,0 feet overall (2004), giving it roughly 6,0 additional feet of deck space compared to the Bennington 165 Si 2004 at 15,0 feet (2004). Weight tells a clearer story for trailering families: the Bennington 2250 RFS 2004 tips the scales at 1 835 lbs — 460 lbs less than the Bennington 165 Si 2004 at 1 375 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 115 hp, the Bennington 2250 RFS 2004 has a 65-hp advantage over the Bennington 165 Si 2004's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Bennington 2250 RFS 2004 carries 26 gallons versus 2 gallons in the Bennington 165 Si 2004. 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 Bennington 2250 RFS 2004 is rated for 11 passengers, while the Bennington 165 Si 2004 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2250 RFS 2004 could be the deciding factor.

Bottom line: Choose the Bennington 2250 RFS 2004 if your priority is putting more people on the water — it handles 11 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Bennington 165 Si 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Bennington 165 Si 2004 vs Bennington 2250 RFS 2004 — Common Questions

Which is the larger boat — the Bennington 165 Si 2004 or the Bennington 2250 RFS 2004?
The Bennington 2250 RFS 2004 is the longer of the two at 21,0 feet overall. The Bennington 165 Si 2004 comes in at 15,0 feet, making it roughly 6,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Bennington 165 Si 2004 or the Bennington 2250 RFS 2004?
For trailering, the Bennington 165 Si 2004 has the edge at 1 375 lbs dry weight versus 1 835 lbs for the Bennington 2250 RFS 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 Bennington 2250 RFS 2004 is rated to a maximum of 115 hp, giving it the larger power ceiling. The Bennington 165 Si 2004 tops out at 50 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 Bennington 165 Si 2004 is Coast Guard rated for 7 passengers, while the Bennington 2250 RFS 2004 is certified for 11. 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 Bennington 2250 RFS 2004 measures 102" wide, compared to 96" for the Bennington 165 Si 2004. 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 Bennington 165 Si 2004 or the Bennington 2250 RFS 2004?
The Bennington 2250 RFS 2004 has the bigger tank at 26 gallons, versus 2 gallons on the Bennington 165 Si 2004. That 24-gallon difference translates to roughly 72–120 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Bennington 165 Si 2004 and Bennington 2250 RFS 2004 from the same manufacturer?
Yes — both the Bennington 165 Si 2004 and the Bennington 2250 RFS 2004 are built by Bennington. 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.
