The Four Winns HD1 OB RS 2021 measures 101" wide, compared to 9" for the Four Winns 170 Horizon 2004. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

The Four Winns HD1 OB RS 2021 has the bigger tank at 32 gallons, versus 24 gallons on the Four Winns 170 Horizon 2004. That 8-gallon difference translates to roughly 24–40 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Detailed Evaluation & Buyer Recommendation

The Four Winns 170 Horizon 2004 vs Four Winns HD1 OB RS 2021 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 HD1 OB RS 2021 tops out at 90 hp. Engine specs for the Four Winns 170 Horizon 2004 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Four Winns HD1 OB RS 2021 carries 32 gallons versus 24 gallons in the Four Winns 170 Horizon 2004. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
