Glastron GX 235 2005 vs Glastron MX 185 2012 — Same Brand, Different Boat

The Glastron GX 235 2005 vs Glastron MX 185 2012 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 270 hp, the Glastron GX 235 2005 has a 50-hp advantage over the Glastron MX 185 2012's 220-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Glastron GX 235 2005 carries 47 gallons versus 24 gallons in the Glastron MX 185 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 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: The Glastron GX 235 2005 at 23,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Glastron MX 185 2012 at 18,4 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.

Glastron GX 235 2005 vs Glastron MX 185 2012 — Common Questions

Which is the larger boat — the Glastron GX 235 2005 or the Glastron MX 185 2012?
The Glastron GX 235 2005 is the longer of the two at 23,0 feet overall. The Glastron MX 185 2012 comes in at 18,4 feet, making it roughly 4,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Glastron GX 235 2005 is rated to a maximum of 270 hp, giving it the larger power ceiling. The Glastron MX 185 2012 tops out at 220 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 Glastron GX 235 2005 is Coast Guard rated for 7 passengers, while the Glastron MX 185 2012 is certified for 7. 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 has the larger fuel tank — the Glastron GX 235 2005 or the Glastron MX 185 2012?
The Glastron GX 235 2005 has the bigger tank at 47 gallons, versus 24 gallons on the Glastron MX 185 2012. That 23-gallon difference translates to roughly 69–115 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Glastron GX 235 2005 and Glastron MX 185 2012 from the same manufacturer?
Yes — both the Glastron GX 235 2005 and the Glastron MX 185 2012 are built by Glastron. 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.
