Detailed Evaluation & Buyer Recommendation

Four Winns 378 Vista 2004 vs Four Winns H310SS 2010: Same Brand, Different Boat

The Four Winns 378 Vista 2004 vs Four Winns H310SS 2010 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 Four Winns H310SS 2010 tops out at 300 hp. Engine specs for the Four Winns 378 Vista 2004 aren't listed - confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Four Winns 378 Vista 2004 carries 300 gallons versus 130 gallons in the Four Winns H310SS 2010. 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 H310SS 2010 is rated for 14 passengers, while the Four Winns 378 Vista 2004 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Four Winns H310SS 2010 could be the deciding factor.

Bottom line: Choose the Four Winns H310SS 2010 if your priority is putting more people on the water - it handles 14 passengers and at 31,3 ft it has the deck room to back that rating up comfortably. The Four Winns 378 Vista 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
