Monterey 243 EX 2008 vs Monterey 318SC 2009 — Same Brand, Different Boat

Matching a modified vee Monterey 243 EX 2008 against a deep vee Monterey 318SC 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Monterey 318SC 2009 measures 31,0 feet overall (2009), giving it roughly 6,0 additional feet of deck space compared to the Monterey 243 EX 2008 at 25,0 feet (2008). At 5 lbs and 85 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.

Both boats share a closely matched power ceiling — 320 hp for the Monterey 243 EX 2008 and 320 hp for the Monterey 318SC 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Monterey 318SC 2009 carries 142 gallons versus 57 gallons in the Monterey 243 EX 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Monterey 243 EX 2008 is rated for up to 7 people. Passenger data for the Monterey 318SC 2009 wasn't available.

Bottom line: The Monterey 318SC 2009 at 31,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey 243 EX 2008 at 25,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Monterey 243 EX 2008 vs Monterey 318SC 2009 — Common Questions

Which is the larger boat — the Monterey 243 EX 2008 or the Monterey 318SC 2009?
The Monterey 318SC 2009 is the longer of the two at 31,0 feet overall. The Monterey 243 EX 2008 comes in at 25,0 feet, making it roughly 6,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Monterey 243 EX 2008 or the Monterey 318SC 2009?
For trailering, the Monterey 243 EX 2008 has the edge at 5 lbs dry weight versus 85 lbs for the Monterey 318SC 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.
How many passengers can the Monterey 243 EX 2008 carry?

Which boat is wider, and does it affect trailering?
The Monterey 318SC 2009 measures 114" wide, compared to 102" for the Monterey 243 EX 2008. 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.
Which boat has the larger fuel tank — the Monterey 243 EX 2008 or the Monterey 318SC 2009?
The Monterey 318SC 2009 has the bigger tank at 142 gallons, versus 57 gallons on the Monterey 243 EX 2008. That 85-gallon difference translates to roughly 255–425 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Monterey 243 EX 2008 and Monterey 318SC 2009 from the same manufacturer?
Yes — both the Monterey 243 EX 2008 and the Monterey 318SC 2009 are built by Monterey. 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.
