Detailed Evaluation & Buyer Recommendation

Four Winns H4 OB 2023 vs Four Winns V378 2009 — Same Brand, Different Boat

The Four Winns H4 OB 2023 vs Four Winns V378 2009 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 Four Winns V378 2009 measures 37,0 feet overall (2009), giving it roughly 13,9 additional feet of deck space compared to the Four Winns H4 OB 2023 at 23,1 feet (2023). Weight tells a clearer story for trailering families: the Four Winns H4 OB 2023 tips the scales at 4 200 lbs — 3 992 lbs more than the Four Winns V378 2009 at 208 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 Four Winns V378 2009 tops out at 550 hp. Engine specs for the Four Winns H4 OB 2023 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Four Winns H4 OB 2023 carries 52 gallons versus 3 gallons in the Four Winns V378 2009. 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 Four Winns V378 2009 is rated for 14 passengers, while the Four Winns H4 OB 2023 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Four Winns V378 2009 could be the deciding factor.

Bottom line: Choose the Four Winns V378 2009 if your priority is putting more people on the water — it handles 14 passengers and at 37,0 ft it has the deck room to back that rating up comfortably. The Four Winns H4 OB 2023 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
