Monterey 258 SS 2019 vs Monterey 350 SY 2007 — Same Brand, Different Boat

The Monterey 258 SS 2019 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.

Size is the most obvious dividing line here. The Monterey 350 SY 2007 measures 37,0 feet overall (2007), giving it roughly 11,9 additional feet of deck space compared to the Monterey 258 SS 2019 at 25,1 feet (2019). Weight tells a clearer story for trailering families: the Monterey 258 SS 2019 tips the scales at 5 100 lbs — 4 935 lbs more than the Monterey 350 SY 2007 at 165 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling — 430 hp for the Monterey 258 SS 2019 and 425 hp for the Monterey 350 SY 2007. 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 258 SS 2019 carries 65 gallons versus 23 gallons in the Monterey 350 SY 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Monterey 258 SS 2019 is rated for up to 7 people. Passenger data for the Monterey 350 SY 2007 wasn't available.

Bottom line: The Monterey 350 SY 2007 at 37,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey 258 SS 2019 at 25,1 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 258 SS 2019 vs Monterey 350 SY 2007 — Common Questions

Which is the larger boat — the Monterey 258 SS 2019 or the Monterey 350 SY 2007?
The Monterey 350 SY 2007 is the longer of the two at 37,0 feet overall. The Monterey 258 SS 2019 comes in at 25,1 feet, making it roughly 11,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Monterey 258 SS 2019 or the Monterey 350 SY 2007?
For trailering, the Monterey 350 SY 2007 has the edge at 165 lbs dry weight versus 5 100 lbs for the Monterey 258 SS 2019. 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 258 SS 2019 carry?
The Monterey 258 SS 2019 has an official capacity rating of 7 people. Capacity data wasn't available for the other model in this comparison — verify directly with the dealer.
Which boat is wider, and does it affect trailering?
The Monterey 350 SY 2007 measures 138" wide, compared to 103" for the Monterey 258 SS 2019. 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 258 SS 2019 or the Monterey 350 SY 2007?
The Monterey 258 SS 2019 has the bigger tank at 65 gallons, versus 23 gallons on the Monterey 350 SY 2007. That 42-gallon difference translates to roughly 126–210 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Monterey 258 SS 2019 and Monterey 350 SY 2007 from the same manufacturer?
Yes — both the Monterey 258 SS 2019 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.
