The BBLADES OB/F OB/F is perhaps the most versatile outboard
A four-blade, stainless steel wheel (14.75” diameter available in one-inch pitch increments from 21- to 32- inches and 15” diameter in one-inch increments from 33- to 37-inches), BBLADES’ OB/F features a custom-tuned exhaust tube that reduces drag, improves trim reaction and aides’ time-to-plane and top-end speed.
The leading edge of each blade is wedged and balanced while the trailing edge cup heights are lengthened and matched for cleaner, smoother acceleration. It’s available in both left- and right-hand rotation.
An exclusive feature of the BBLADES OB/F is its 7/8th-inch tunable exhaust vents with plugs that allow boaters to customize the necessary propeller ventilation for their specific boat set-up and improve planning. Other propeller companies only offer a non-tunable one-inch vent or a 5/8th-inch tunable vent. They also require a different propeller for two-stroke and four-stroke applications, while BBLADES has found the formula that makes the BBLADES OB/F ideal for any 150 to 300 horsepower outboard from any manufacturer in a single propeller option.
“For a boating application that requires aggressive ventilation, the BBLADES OB/F has a massive tuning capacity; up to 3.5-inches of ventilation, which allows the boater to control the aeration around the propeller. The overall design is to optimize both hole-shot and
After the customization is completed, BBLADES finishes the prop to a high-polish that makes the BBLADES OB/F look as good as it runs. Priced at just $797, the BBLADES OB/F is one of the least expensive performance enhancements a boater can buy, and boaters who want a little something extra can inquire about the lab-finished versions.
