The Monterey 243 EX 2007 vs Monterey 258 SS 2019 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 258 SS 2019 measures 25,1 feet overall (2019), giving it roughly 3,1 additional feet of deck space compared to the Monterey 243 EX 2007 at 22,0 feet (2007). At 5 000 lbs and 5 100 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 430 hp, the Monterey 258 SS 2019 has a 110-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 258 SS 2019 carries 65 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.

For family outings this is probably the sharpest distinction between the two. The Monterey 258 SS 2019 is rated for 7 passengers, while the Monterey 243 EX 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Monterey 258 SS 2019 could be the deciding factor.
