Maxum 3100 SE 2009 vs Maxum 4200 SY 2007 - Boat Spec Comparison

Q: Which is the larger boat — the Maxum 3100 SE 2009 or the Maxum 4200 SY 2007?

The Maxum 4200 SY 2007 is the longer of the two at 42,0 feet overall. The Maxum 3100 SE 2009 comes in at 33,0 feet, making it roughly 9,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Maxum 3100 SE 2009 or the Maxum 4200 SY 2007?

For trailering, the Maxum 4200 SY 2007 has the edge at 357 lbs dry weight versus 12 838 lbs for the Maxum 3100 SE 2009. 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 3100 SE 2009 has a documented max rating of 375 hp. Engine specifications for the Maxum 4200 SY 2007 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 3100 SE 2009 is Coast Guard rated for 10 passengers, while the Maxum 4200 SY 2007 is certified for 13. 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 4200 SY 2007 measures 166" wide, compared to 127" for the Maxum 3100 SE 2009. 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 3100 SE 2009 or the Maxum 4200 SY 2007?

The Maxum 3100 SE 2009 has the bigger tank at 165 gallons, versus 48 gallons on the Maxum 4200 SY 2007. That 117-gallon difference translates to roughly 351–585 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Maxum 3100 SE 2009 and Maxum 4200 SY 2007 from the same manufacturer?

Yes — both the Maxum 3100 SE 2009 and the Maxum 4200 SY 2007 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 3100 SE 2009 vs Maxum 4200 SY 2007 — Same Brand, Different Boat

The Maxum 3100 SE 2009 vs Maxum 4200 SY 2007 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 4200 SY 2007 measures 42,0 feet overall (2007), giving it roughly 9,0 additional feet of deck space compared to the Maxum 3100 SE 2009 at 33,0 feet (2009). Weight tells a clearer story for trailering families: the Maxum 3100 SE 2009 tips the scales at 12 838 lbs — 12 481 lbs more than the Maxum 4200 SY 2007 at 357 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 3100 SE 2009 carries a rated maximum of 375 hp. Engine data for the Maxum 4200 SY 2007 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Maxum 3100 SE 2009 carries 165 gallons versus 48 gallons in the Maxum 4200 SY 2007. 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 4200 SY 2007 is rated for 13 passengers, while the Maxum 3100 SE 2009 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 4200 SY 2007 could be the deciding factor.

Bottom line: Choose the Maxum 4200 SY 2007 if your priority is putting more people on the water — it handles 13 passengers and at 42,0 ft it has the deck room to back that rating up comfortably. The Maxum 3100 SE 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
