Bennington 17 SLi 2011 vs Bennington 2575 RLTDIO 2006 — Same Brand, Different Boat

The Bennington 17 SLi 2011 vs Bennington 2575 RLTDIO 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 Bennington 2575 RLTDIO 2006 tops out at 8 hp. Engine specs for the Bennington 17 SLi 2011 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Bennington 2575 RLTDIO 2006 is rated for 7 passengers, while the Bennington 17 SLi 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2575 RLTDIO 2006 could be the deciding factor.

The Bennington 2575 RLTDIO 2006 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Bennington 17 SLi 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Choose the Bennington 2575 RLTDIO 2006 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 Bennington 17 SLi 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Which is the larger boat — the Bennington 17 SLi 2011 or the Bennington 2575 RLTDIO 2006?
The Bennington 2575 RLTDIO 2006 is the longer of the two at 25,0 feet overall. The Bennington 17 SLi 2011 comes in at 17,4 feet, making it roughly 7,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
What is the maximum horsepower rating for these boats?
The Bennington 2575 RLTDIO 2006 has a documented max rating of 8 hp. Engine specifications for the Bennington 17 SLi 2011 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Bennington 17 SLi 2011 is Coast Guard rated for 5 passengers, while the Bennington 2575 RLTDIO 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Bennington 17 SLi 2011 and Bennington 2575 RLTDIO 2006 share an 8 ft. 6 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Are the Bennington 17 SLi 2011 and Bennington 2575 RLTDIO 2006 from the same manufacturer?
Yes — both the Bennington 17 SLi 2011 and the Bennington 2575 RLTDIO 2006 are built by Bennington.
