The Triton Boats 190LTS 2005 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 15,0 additional feet of deck space compared to the Triton Boats 190LTS 2005 at 19,0 feet (2005). Weight tells a clearer story for trailering families: the Triton Boats 351 Express 2007 tips the scales at 9 432 lbs — 9 267 lbs less than the Triton Boats 190LTS 2005 at 165 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 750-hp advantage over the Triton Boats 190LTS 2005's 150-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 55 gallons in the Triton Boats 190LTS 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 351 Express 2007 is rated for 12 passengers, while the Triton Boats 190LTS 2005 caps at 5. 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.
Bottom line: Choose the Triton Boats 351 Express 2007 if your priority is putting more people on the water — it handles 12 passengers and at 34,0 ft it has the deck room to back that rating up comfortably. The Triton Boats 190LTS 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.
