Maxum 2100SD Sport Deck 2005 vs Maxum 3700 SY 2008 - Boat Spec Comparison

Q: Which is easier to trailer — the Maxum 2100SD Sport Deck 2005 or the Maxum 3700 SY 2008?

For trailering, the Maxum 3700 SY 2008 has the edge at 1 932 lbs dry weight versus 3 928 lbs for the Maxum 2100SD Sport Deck 2005. 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 3700 SY 2008 has a documented max rating of 420 hp. Engine specifications for the Maxum 2100SD Sport Deck 2005 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 2100SD Sport Deck 2005 is Coast Guard rated for 6 passengers, while the Maxum 3700 SY 2008 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.

Q: Which boat is wider, and does it affect trailering?

The Maxum 3700 SY 2008 measures 156" wide, compared to 102" for the Maxum 2100SD Sport Deck 2005. 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 2100SD Sport Deck 2005 or the Maxum 3700 SY 2008?

The Maxum 2100SD Sport Deck 2005 has the bigger tank at 55 gallons, versus 3 gallons on the Maxum 3700 SY 2008. That 52-gallon difference translates to roughly 156–260 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Maxum 2100SD Sport Deck 2005 and Maxum 3700 SY 2008 from the same manufacturer?

Yes — both the Maxum 2100SD Sport Deck 2005 and the Maxum 3700 SY 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 2100SD Sport Deck 2005 vs Maxum 3700 SY 2008 — Same Brand, Different Boat

The Maxum 2100SD Sport Deck 2005 vs Maxum 3700 SY 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.

The Maxum 3700 SY 2008 tops out at 420 hp. Engine specs for the Maxum 2100SD Sport Deck 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Maxum 2100SD Sport Deck 2005 carries 55 gallons versus 3 gallons in the Maxum 3700 SY 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 3700 SY 2008 is rated for 11 passengers, while the Maxum 2100SD Sport Deck 2005 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 3700 SY 2008 could be the deciding factor.

Bottom line: Choose the Maxum 3700 SY 2008 if your priority is putting more people on the water — it handles 11 passengers and at 37,0 ft it has the deck room to back that rating up comfortably. The Maxum 2100SD Sport Deck 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
