Monterey 340SY 2009 vs Monterey 350 SY 2007 — Same Brand, Different Boat

The Monterey 340SY 2009 vs Monterey 350 SY 2007 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.

On paper these two are close siblings in the size department — Monterey 340SY 2009 at 35,0 ft versus Monterey 350 SY 2007 at 37,0 ft. At 142 lbs and 165 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 425 hp, the Monterey 350 SY 2007 has a 50-hp advantage over the Monterey 340SY 2009's 375-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 21 gal and 23 gal — so range won't be a tiebreaker here.

Bottom line: Performance buyers should lean toward the Monterey 350 SY 2007 and its 425-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Monterey 340SY 2009 with its 375-hp rating is the more economical daily driver.

Monterey 340SY 2009 vs Monterey 350 SY 2007 — Common Questions

Which is the larger boat — the Monterey 340SY 2009 or the Monterey 350 SY 2007?
The Monterey 350 SY 2007 is the longer of the two at 37,0 feet overall. The Monterey 340SY 2009 comes in at 35,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Monterey 340SY 2009 or the Monterey 350 SY 2007?
For trailering, the Monterey 340SY 2009 has the edge at 142 lbs dry weight versus 165 lbs for the Monterey 350 SY 2007. 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.
Which boat can handle a bigger outboard?
The Monterey 350 SY 2007 is rated to a maximum of 425 hp, giving it the larger power ceiling. The Monterey 340SY 2009 tops out at 375 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.
Which boat is wider, and does it affect trailering?
The Monterey 350 SY 2007 measures 138" wide, compared to 135" for the Monterey 340SY 2009. 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.
How do the fuel tanks compare on the Monterey 340SY 2009 and Monterey 350 SY 2007?
Both boats carry similar fuel loads — 21 gallons and 23 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Monterey 340SY 2009 and Monterey 350 SY 2007 from the same manufacturer?
Yes — both the Monterey 340SY 2009 and the Monterey 350 SY 2007 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.
