Monterey 400SY 2008 vs Monterey M3 MSX 2012 - Boat Spec Comparison

Q: Which is the larger boat - the Monterey 400SY 2008 or the Monterey M3 MSX 2012?

The Monterey 400SY 2008 is the longer of the two at 41,0 feet overall. The Monterey M3 MSX 2012 comes in at 23,8 feet, making it roughly 17,2 ft shorter - a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Monterey 400SY 2008 is rated to a maximum of 375 hp, giving it the larger power ceiling. The Monterey M3 MSX 2012 tops out at 320 hp. Keep in mind that maximum ratings are just that - matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many passengers can the Monterey 400SY 2008 carry?

The Monterey 400SY 2008 has an official capacity rating of 12 people. Capacity data wasn't available for the other model in this comparison - verify directly with the dealer.

Q: Which boat is wider, and does it affect trailering?

The Monterey 400SY 2008 measures 150" wide, compared to 102" for the Monterey M3 MSX 2012. 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.

Q: Which boat has the larger fuel tank - the Monterey 400SY 2008 or the Monterey M3 MSX 2012?

The Monterey 400SY 2008 has the bigger tank at 330 gallons, versus 50 gallons on the Monterey M3 MSX 2012. That 280-gallon difference translates to roughly 840–1400 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Monterey 400SY 2008 and Monterey M3 MSX 2012 from the same manufacturer?

Yes - both the Monterey 400SY 2008 and the Monterey M3 MSX 2012 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.

Detailed Evaluation & Buyer Recommendation

Monterey 400SY 2008 vs Monterey M3 MSX 2012: Same Brand, Different Boat

The Monterey 400SY 2008 is a modified-V design and the Monterey M3 MSX 2012 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

The power gap is worth calling out. Rated to 375 hp, the Monterey 400SY 2008 has a 55-hp advantage over the Monterey M3 MSX 2012'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 400SY 2008 carries 330 gallons versus 50 gallons in the Monterey M3 MSX 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Monterey 400SY 2008 is rated for up to 12 people. Passenger data for the Monterey M3 MSX 2012 wasn't available.

Bottom line: The Monterey 400SY 2008 at 41,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey M3 MSX 2012 at 23,8 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.
