The Triton Boats 173 Sport 2006 vs Triton Boats 351 Express 2007 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.

Size is the most obvious dividing line here. The Triton Boats 351 Express 2007 measures 34,0 feet overall (2007), giving it roughly 17,0 additional feet of deck space compared to the Triton Boats 173 Sport 2006 at 17,0 feet (2006). Weight tells a clearer story for trailering families: the Triton Boats 351 Express 2007 tips the scales at 9 432 lbs — 9 339 lbs less than the Triton Boats 173 Sport 2006 at 93 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 900 hp, the Triton Boats 351 Express 2007 has a 820-hp advantage over the Triton Boats 173 Sport 2006'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 351 Express 2007 carries 355 gallons versus 18 gallons in the Triton Boats 173 Sport 2006. 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 351 Express 2007 is rated for 12 passengers, while the Triton Boats 173 Sport 2006 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 351 Express 2007 could be the deciding factor.
