The G3 Boats HP170 2006 vs G3 Boats Prop Tunnel 1860 CCT DLX 2013 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.

Rated to 115 hp, the G3 Boats HP170 2006 has a 25-hp advantage over the G3 Boats Prop Tunnel 1860 CCT DLX 2013's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
