Maxum 1800MX Sport Boat 2005 vs Maxum 2100 SC3 2009 — Same Brand, Different Boat

The Maxum 1800MX Sport Boat 2005 vs Maxum 2100 SC3 2009 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 Maxum 2100 SC3 2009 tops out at 300 hp. Engine specs for the Maxum 1800MX Sport Boat 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Maxum 2100 SC3 2009 carries 55 gallons versus 21 gallons in the Maxum 1800MX Sport Boat 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Maxum 2100 SC3 2009 is rated for 6 passengers, while the Maxum 1800MX Sport Boat 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 2100 SC3 2009 could be the deciding factor.

Bottom line: Choose the Maxum 2100 SC3 2009 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Maxum 1800MX Sport Boat 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
