The diffuser ring prevents exhaust gasses from re-entering the blades at low speeds by preventing them from entering the blade. It only aids in preventing cavitation and, in the worst-case scenario, complete blow-out of a thru-hub exhaust system by keeping the exhaust gasses in the slipstream (the water flow between the bottom unit and the propeller hub) from causing cavitation (total loss of propeller "grip"). Your propeller may be slipping if you don't have one. Whether you're practicing your casting, snorkeling the outstanding marine life, or simply drifting on the open sea for pleasure, you'll need to equip your boat with the greatest equipment to ensure that nothing interrupts your fantastic recreational time.
Key Features:
- It has an outward flare to prevent exhaust gas from re-entering the blades and lowering thrust.
- As a result of the exhaust, it prevents the prop from breaking.
