When two boats share the same hull type — in this case both the Vectra 2050 IO 2008 and the Vectra V-172 OB Fish 2007 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Vectra V-172 OB Fish 2007 measures 16,0 feet overall (2007), giving it roughly 14,0 additional feet of deck space compared to the Vectra 2050 IO 2008 at 2,0 feet (2008). At 238 lbs and 152 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The Vectra V-172 OB Fish 2007 tops out at 130 hp. Engine specs for the Vectra 2050 IO 2008 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Vectra 2050 IO 2008 carries 51 gallons versus 23 gallons in the Vectra V-172 OB Fish 2007. 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 Vectra 2050 IO 2008 is rated for 12 passengers, while the Vectra V-172 OB Fish 2007 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Vectra 2050 IO 2008 could be the deciding factor.
Bottom line: Choose the Vectra 2050 IO 2008 if your priority is putting more people on the water — it handles 12 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Vectra V-172 OB Fish 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
