About Stiletto Boat Propellers

Advantage Q + Guardian Hub Stainless Steel Boat Propellers

  • Excellent hole shot, strong mid-range acceleration, and top speed describe the Stiletto ADVANTAGE Q Stainless Steel Boat Propeller Series. This series gives you the advantage when skiing, carrying loads and in adverse water conditions. This is the choice for all around performance; its your ADVANTAGE. Stiletto props are made in the USA.

  • ADVANTAGE Q utilizes the Stiletto Guardian Hub system.

SUPERIOR BLADE DESIGN - Stiletto Propellers are truly the stainless edge. All Stiletto Propellers are of a progressive pitch design. Cupped blades help reduce the chance of cavitation, therefore, increasing the efficiency and performance of your engine.

TOTAL PERFORMANCE - Stiletto Propellers are designed to help each boat and engine combination achieve its peak performance at all throttle levels: low end, mid-range, and top end. Stiletto Propellers are designed to outperform the mass produced aluminum and stainless steel stock/utility propellers. Stiletto props are made in the USA.

RELIABILITY - Stiletto Propellers are one-piece investment cast for exceptional strength and safety. This manufacturing process provides superior consistency in blade shape and accuracy in pitch. Some so-called performance propellers are produced using welded-on blades, which are not as structurally sound nor are they as reliable as a one-piece casting.
