At 14\" diameter and 21\" pitch, this is a high-performance option designed for larger outboards where top-end speed and midrange efficiency are the priority. The 4-blade design adds stern lift and improves handling compared to a 3-blade at the same pitch, making it a strong choice for heavier hulls or boats that need better hole shot and stability at speed.\u003c\/p\u003e\n\n\u003cp\u003eAs part of the Rubex interchangeable system, the propeller housing separates from the hub — so if the blades are damaged, you only replace the housing, not the entire assembly. The hub is reusable in most cases, which significantly reduces the cost of propeller replacement over time.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-blade design\u003c\/strong\u003e — improved stern lift, smoother ride, and better handling versus a 3-blade at equivalent pitch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSqueeze-cast aluminum construction\u003c\/strong\u003e — denser grain structure than die-cast for stiffer, more efficient blades with less flex under load\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e14\" x 21\" — high-pitch configuration\u003c\/strong\u003e for top-end speed on larger, higher-horsepower outboards\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eRight-hand (standard) rotation\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRubex interchangeable hub system\u003c\/strong\u003e — replace only the housing if damaged; hub is reusable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub kit required — sold separately\u003c\/strong\u003e (see compatible hub kits below)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatible Hub Kits (Sold Separately)\u003c\/h3\u003e\n\u003cp\u003eThis propeller requires a Rubex interchangeable hub kit matched to your engine.

The 4-blade configuration is the right call when a customer is stepping up from a 3-blade and wants better stern lift, reduced porpoising, or a smoother ride at cruise — without sacrificing top-end speed. If a customer is lugging below WOT RPM with this pitch, step them down to the \u003ca href=\"\/products\/11124724269092\"\u003e14.25x19\u003c\/a\u003e or \u003ca href=\"\/products\/11124724629540\"\u003e14.5x17\u003c\/a\u003e.
