Monterey 350 SY 2008 vs Monterey M-20 2019 — Same Brand, Different Boat

The Monterey 350 SY 2008 vs Monterey M-20 2019 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 2008 measures 37,0 feet overall (2008), giving it roughly 14,8 additional feet of deck space compared to the Monterey M-20 2019 at 22,2 feet (2019). Weight tells a clearer story for trailering families: the Monterey M-20 2019 tips the scales at 3 500 lbs — 3 335 lbs less than the Monterey 350 SY 2008 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.

The power gap is worth calling out. Rated to 425 hp, the Monterey 350 SY 2008 has a 145-hp advantage over the Monterey M-20 2019's 280-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 M-20 2019 carries 36 gallons versus 23 gallons in the Monterey 350 SY 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Monterey 350 SY 2008 at 37,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Monterey M-20 2019 at 22,2 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 350 SY 2008 vs Monterey M-20 2019 — Common Questions

Which is the larger boat — the Monterey 350 SY 2008 or the Monterey M-20 2019?
The Monterey 350 SY 2008 is the longer of the two at 37,0 feet overall. The Monterey M-20 2019 comes in at 22,2 feet, making it roughly 14,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Monterey 350 SY 2008 or the Monterey M-20 2019?
For trailering, the Monterey 350 SY 2008 has the edge at 165 lbs dry weight versus 3 500 lbs for the Monterey M-20 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.
Which boat can handle a bigger outboard?
The Monterey 350 SY 2008 is rated to a maximum of 425 hp, giving it the larger power ceiling. The Monterey M-20 2019 tops out at 280 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.
How many passengers can the Monterey M-20 2019 carry?
The Monterey M-20 2019 has an official capacity rating of 6 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 2008 measures 138" wide, compared to 101" for the Monterey M-20 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 350 SY 2008 or the Monterey M-20 2019?
The Monterey M-20 2019 has the bigger tank at 36 gallons, versus 23 gallons on the Monterey 350 SY 2008. That 13-gallon difference translates to roughly 39–65 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Monterey 350 SY 2008 and Monterey M-20 2019 from the same manufacturer?
Yes — both the Monterey 350 SY 2008 and the Monterey M-20 2019 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.
