Detailed Evaluation & Buyer Recommendation

Triton Boats 173 Sport 2007 vs Triton Boats TR-186 PD 2005 — Same Brand, Different Boat

The Triton Boats 173 Sport 2007 vs Triton Boats TR-186 PD 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 power gap is worth calling out. Rated to 175 hp, the Triton Boats TR-186 PD 2005 has a 95-hp advantage over the Triton Boats 173 Sport 2007's 80-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Bottom line: Performance buyers should lean toward the Triton Boats TR-186 PD 2005 and its 175-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Triton Boats 173 Sport 2007 with its 80-hp rating is the more economical daily driver.
