The ProCraft 170 Combo 2005 vs ProCraft 175 Pro SC 2004 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.
Both boats share a closely matched power ceiling — 125 hp for the ProCraft 170 Combo 2005 and 125 hp for the ProCraft 175 Pro SC 2004. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 25 gal and 25 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The ProCraft 170 Combo 2005 is rated for 5 passengers, while the ProCraft 175 Pro SC 2004 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ProCraft 170 Combo 2005 could be the deciding factor.
Bottom line: Choose the ProCraft 170 Combo 2005 if your priority is putting more people on the water — it handles 5 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The ProCraft 175 Pro SC 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
