Monterey 234 FSX 2007 vs Monterey 400SY 2008 - Boat Spec Comparison

Q: Which is the larger boat — the Monterey 234 FSX 2007 or the Monterey 400SY 2008?

The Monterey 400SY 2008 is the longer of the two at 41,0 feet overall. The Monterey 234 FSX 2007 comes in at 24,0 feet, making it roughly 17,0 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 234 FSX 2007 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 234 FSX 2007 measures 102" wide, compared to 15" for the Monterey 400SY 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.

Q: Which boat has the larger fuel tank — the Monterey 234 FSX 2007 or the Monterey 400SY 2008?

The Monterey 234 FSX 2007 has the bigger tank at 62 gallons, versus 33 gallons on the Monterey 400SY 2008. That 29-gallon difference translates to roughly 87–145 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Monterey 234 FSX 2007 and Monterey 400SY 2008 from the same manufacturer?

Yes — both the Monterey 234 FSX 2007 and the Monterey 400SY 2008 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 234 FSX 2007 vs Monterey 400SY 2008 — Same Brand, Different Boat

The Monterey 234 FSX 2007 vs Monterey 400SY 2008 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.

The power gap is worth calling out. Rated to 375 hp, the Monterey 400SY 2008 has a 55-hp advantage over the Monterey 234 FSX 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 234 FSX 2007 carries 62 gallons versus 33 gallons in the Monterey 400SY 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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 234 FSX 2007 at 24,0 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.
