Maxum 2100 SD 2007 vs Maxum 3100 SE 2008 - Boat Spec Comparison

Q: Which is the larger boat — the Maxum 2100 SD 2007 or the Maxum 3100 SE 2008?

The Maxum 2100 SD 2007 is the longer of the two at 21,0 feet overall. The Maxum 3100 SE 2008 comes in at 3,0 feet, making it roughly 18,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Maxum 2100 SD 2007 or the Maxum 3100 SE 2008?

For trailering, the Maxum 2100 SD 2007 has the edge at 3 953 lbs dry weight versus 10 765 lbs for the Maxum 3100 SE 2008. 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.

Q: What is the maximum horsepower rating for these boats?

The Maxum 2100 SD 2007 has a documented max rating of 300 hp. Engine specifications for the Maxum 3100 SE 2008 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

Q: How many people can each boat hold?

The Maxum 2100 SD 2007 is Coast Guard rated for 6 passengers, while the Maxum 3100 SE 2008 is certified for 9. 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 is wider, and does it affect trailering?

The Maxum 3100 SE 2008 measures 126" wide, compared to 102" for the Maxum 2100 SD 2007. 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.

Q: Which boat has the larger fuel tank — the Maxum 2100 SD 2007 or the Maxum 3100 SE 2008?

The Maxum 2100 SD 2007 has the bigger tank at 55 gallons, versus 15 gallons on the Maxum 3100 SE 2008. That 40-gallon difference translates to roughly 120–200 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Maxum 2100 SD 2007 and Maxum 3100 SE 2008 from the same manufacturer?

Yes — both the Maxum 2100 SD 2007 and the Maxum 3100 SE 2008 are built by Maxum. 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

Maxum 2100 SD 2007 vs Maxum 3100 SE 2008 — Same Brand, Different Boat

The Maxum 2100 SD 2007 vs Maxum 3100 SE 2008 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 Maxum 2100 SD 2007 measures 21,0 feet overall (2007), giving it roughly 18,0 additional feet of deck space compared to the Maxum 3100 SE 2008 at 3,0 feet (2008). Weight tells a clearer story for trailering families: the Maxum 3100 SE 2008 tips the scales at 10 765 lbs — 6 812 lbs less than the Maxum 2100 SD 2007 at 3 953 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 Maxum 2100 SD 2007 carries a rated maximum of 300 hp. Engine data for the Maxum 3100 SE 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Maxum 2100 SD 2007 carries 55 gallons versus 15 gallons in the Maxum 3100 SE 2008. 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 Maxum 3100 SE 2008 is rated for 9 passengers, while the Maxum 2100 SD 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 3100 SE 2008 could be the deciding factor.

Bottom line: Choose the Maxum 3100 SE 2008 if your priority is putting more people on the water — it handles 9 passengers and at 3,0 ft it has the deck room to back that rating up comfortably. The Maxum 2100 SD 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
