The Monterey 233 EX Explorer 2006 vs Monterey 400SY 2013 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 400SY 2013 measures 41,0 feet overall (2013), giving it roughly 19,0 additional feet of deck space compared to the Monterey 233 EX Explorer 2006 at 22,0 feet (2006). At 5 lbs and 22 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 435 hp, the Monterey 400SY 2013 has a 115-hp advantage over the Monterey 233 EX Explorer 2006'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 233 EX Explorer 2006 carries 57 gallons versus 33 gallons in the Monterey 400SY 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Monterey 233 EX Explorer 2006 is rated for up to 6 people. Passenger data for the Monterey 400SY 2013 wasn't available.
