Turning Point Propellers 21431111 14x11 3-Blade Aluminum RH Propeller for Honda BF75/BF90/BF115/BF130 & Mercury/Mariner 40-150HP

The Turning Point Propellers 21431111 is a 14 x 11 inch aluminum outboard propeller featuring 3 blades and right-hand (RH) rotation. Cast aluminum construction delivers dependable, everyday performance at a lower cost than stainless steel propellers, making it a practical choice for boaters who need a reliable replacement prop without the stainless price tag. The 14 x 11 diameter-and-pitch combination is engineered to match the specific outboard applications listed below, so engine load and RPM stay in the manufacturer's intended range rather than being guessed at.

This propeller is built for outboards rated from roughly 40 HP up through 150 HP, covering both Honda four-stroke and Mercury/Mariner two-stroke and four-stroke engine families. It cross-references directly to OEM part numbers 507 and 11500700, so it can be ordered as a like-for-like replacement using either the Turning Point part number or the corresponding OEM number. At 6.3 pounds, it installs the same way as the OEM aluminum propeller it replaces, using standard propeller shaft hardware.
