Mercury Enertia Stainless Steel Propeller – 3-Blade, 15" × 15", Right-Hand (8M0151231)

The Mercury Enertia 3-Blade Stainless Steel Propeller (part number 8M0151231) was designed for maximum overall performance and is ideal for heavy pontoon boats, offshore center consoles, and Sterndrive runabouts. With a 15-inch diameter and a 15-inch pitch, it offers a balanced combination of acceleration, top speed, and excellent control.

The specially designed blade geometry provides exceptional grip in turns, reduces cavitation, and prevents blow-out—even during tight maneuvers or when towing water sports enthusiasts. The result is precise handling, increased safety, and confident performance, even in demanding conditions.

X7® Stainless Steel Alloy

The Enertia propeller is made from the exclusive Mercury X7® stainless steel alloy. This material is approximately 30% stronger and four times more durable than conventional stainless steel. This allows the blades to be designed thinner, increasing efficiency without sacrificing strength.

Flo‑Torq® SSR / SSR HD Compatible

The Enertia is compatible with Mercury Flo‑Torq® SSR (1-inch propeller shaft) and SSR HD (1.25-inch propeller shaft) hub systems. These systems significantly reduce noise and vibration during shifting and ensure exceptionally smooth operation.
Note: The Flo‑Torq hub kit is not included and must be ordered separately.
