The Monterey 243 EX 2007 vs Monterey 340SY 2012 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 Monterey 340SY 2012 measures 35,3 feet overall (2012), giving it roughly 13,3 additional feet of deck space compared to the Monterey 243 EX 2007 at 22,0 feet (2007). Weight tells a clearer story for trailering families: the Monterey 340SY 2012 tips the scales at 14 700 lbs - 9 700 lbs less than the Monterey 243 EX 2007 at 5 000 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 power gap is worth calling out. Rated to 400 hp, the Monterey 340SY 2012 has a 80-hp advantage over the Monterey 243 EX 2007's 320-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Monterey 340SY 2012 carries 210 gallons versus 57 gallons in the Monterey 243 EX 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Monterey 243 EX 2007 is rated for up to 6 people. Passenger data for the Monterey 340SY 2012 wasn't available.
