The Triton Boats 173 Sport 2005 vs Triton Boats 240 LTS Pro 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 power gap is worth calling out. Rated to 300 hp, the Triton Boats 240 LTS Pro 2009 has a 220-hp advantage over the Triton Boats 173 Sport 2005's 80-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Triton Boats 240 LTS Pro 2009 carries 79 gallons versus 18 gallons in the Triton Boats 173 Sport 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 Triton Boats 240 LTS Pro 2009 is rated for 7 passengers, while the Triton Boats 173 Sport 2005 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats 240 LTS Pro 2009 could be the deciding factor.
