HONDA Engines
KDPropellers, also known as KDP (King Dolphin Propellers) are truly the best choice for your HONDA Outboard! Their 7X Series pressed rubber hub product line includes propellers for horsepower ranges of 9.9 to 250hp and includes Propeller Class: A,B,C,D,E. KDPropellers are manufactured by Parts Korea in South Korea under the highest standard of quality control and attention to detail.
KDPropeller has adopted, developed, and refined the world’s first application of low-pressure casting in its propeller manufacturing process thereby avoiding common casting defects found in todays propeller brands. Their process minimizes defects in the alloy structure while applying pressure when the molten alloy inside the furnace is injected into the propeller mold. This unique process, unlike all other casting methods, ensures a dense molecular structure with precise strength and ductility.
KDP continues to lead the Marine Industry providing a High Peformance product that is Excellent Quality, Reliable, at a Reasonable Price.

HIGH-STRENGTH ALLOY (7X SERIES)
- LIGHT AS ALUMINUM
- DURABLE AS TITANIUM
- RELIABLE AS STAINLESS STEEL
With over 10,000 compression, yield strength, tensile strength, and stretch rate tests over man years, they have now produced a special High-Strength Alloy that is Light as Aluminum, Durable as Titanium, and Reliable as Stainless Steel. KDPropellers are the truly BEST OF ALL WORLDS!
Focusing on “YIELD STRENGTH”, which is a propeller’s mechanical property strength to resist deformation of the blade while trying to maintain its original shape from the applied outside forces when rotating at high horsepower high speed operation, KDPropeller is unmatched in its results for best of all worlds characteristics of light weight, durability and yield strength on par with stainless steel (see image below).
When analyzing the KDPropeller High Strength Alloy yield strength testing to other well known manufactures, the results were clear:
- KDP 7X Series H.S.A has a yield strength of approximately 200 MPa
- Stainless Steel propellers had an average yield strength of 205 MPa
- Aluminum propellers had an average yield strength of 110 MPa

REDUCES CAVITATION
KDPropeller's unique design reduces propeller cavitation in three ways, (1) by minimizing the blade thickness, (2) incorporating a cupping technique, and (3) using the blades flawless design of its leading and trailing edges.
Propeller blade thickness directly affects how much cavitation a propeller will have; the KDPropeller design keeps the blade as thin as possible due our unique High-Strength-Alloy (H.S.A) and casting process. The result is . . . INCREASED PERFORMANCE, HIGH-YIELD STRENGTH, and CAVITATION REDUCTION.
