Maxum 1800MX Sport Boat 2006 vs Maxum 1900 SR3 2008 — Same Brand, Different Boat

The Maxum 1800MX Sport Boat 2006 vs Maxum 1900 SR3 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.

On paper these two are close siblings in the size department — Maxum 1800MX Sport Boat 2006 at 17,0 ft versus Maxum 1900 SR3 2008 at 19,0 ft. Weight tells a clearer story for trailering families: the Maxum 1900 SR3 2008 tips the scales at 2 987 lbs — 996 lbs less than the Maxum 1800MX Sport Boat 2006 at 1 991 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 260 hp, the Maxum 1900 SR3 2008 has a 125-hp advantage over the Maxum 1800MX Sport Boat 2006's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Maxum 1900 SR3 2008 carries 35 gallons versus 21 gallons in the Maxum 1800MX Sport Boat 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Maxum 1900 SR3 2008 and its 260-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Maxum 1800MX Sport Boat 2006 with its 135-hp rating is the more economical daily driver.

Maxum 1800MX Sport Boat 2006 vs Maxum 1900 SR3 2008 — Common Questions

Which is the larger boat — the Maxum 1800MX Sport Boat 2006 or the Maxum 1900 SR3 2008?
The Maxum 1900 SR3 2008 is the longer of the two at 19,0 feet overall. The Maxum 1800MX Sport Boat 2006 comes in at 17,0 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 Maxum 1800MX Sport Boat 2006 or the Maxum 1900 SR3 2008?
For trailering, the Maxum 1800MX Sport Boat 2006 has the edge at 1 991 lbs dry weight versus 2 987 lbs for the Maxum 1900 SR3 2008. 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 Maxum 1900 SR3 2008 is rated to a maximum of 260 hp, giving it the larger power ceiling. The Maxum 1800MX Sport Boat 2006 tops out at 135 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 people can each boat hold?
The Maxum 1800MX Sport Boat 2006 is Coast Guard rated for 5 passengers, while the Maxum 1900 SR3 2008 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Maxum 1900 SR3 2008 measures 95" wide, compared to 84" for the Maxum 1800MX Sport Boat 2006. 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 Maxum 1800MX Sport Boat 2006 or the Maxum 1900 SR3 2008?
The Maxum 1900 SR3 2008 has the bigger tank at 35 gallons, versus 21 gallons on the Maxum 1800MX Sport Boat 2006. That 14-gallon difference translates to roughly 42–70 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Maxum 1800MX Sport Boat 2006 and Maxum 1900 SR3 2008 from the same manufacturer?
Yes — both the Maxum 1800MX Sport Boat 2006 and the Maxum 1900 SR3 2008 are built by Maxum. 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.
