Detailed Evaluation & Buyer Recommendation

Maxum 1800 SR3 2007 vs Maxum 1800MX Sport Boat 2005 — Same Brand, Different Boat

The Maxum 1800 SR3 2007 vs Maxum 1800MX Sport Boat 2005 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 1800 SR3 2007 carries a rated maximum of 220 hp. Engine data for the Maxum 1800MX Sport Boat 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Maxum 1800 SR3 2007 carries 28 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.

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: The Maxum 1800 SR3 2007 and Maxum 1800MX Sport Boat 2005 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
