The Maxum 2900 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 12,0 additional feet of deck space compared to the Maxum 2900 SE 2009 at 30,0 feet (2009). Weight tells a clearer story for trailering families: the Maxum 4200 SY 2007 tips the scales at 35 700 lbs - 25 513 lbs less than the Maxum 2900 SE 2009 at 10 187 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 2900 SE 2009 carries a rated maximum of 300 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 4200 SY 2007 carries 480 gallons versus 125 gallons in the Maxum 2900 SE 2009. 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 2900 SE 2009 caps at 9. 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.
