Boat Propeller, 13 1/2 x 15, for Yamaha Outboard 50-130 HP Motors, 15 Tooth Spline, 3-Blade, RH

Bought the 13 1/2 X15 to go on a 27-ft pontoon boat with a 120 Force outboard to replace a prop I just put on a month ago that got damaged on a sandbar, so we'll keep the damaged one as a spare. As far as the prop itself, it is made with quality material and has a great smooth finish. The rubber and spline are solid with plenty of Gap for exhaust gases. The propeller is pretty easy to install with the correct tools.

My crazy brother keeps a spare propeller in his boat because he learned the hard way that underwater stumps don't care how expensive your weekend plans are. This aluminum propeller arrived with a smooth finish, consistent blade shape, and a properly machined 15-tooth spline hub. The casting quality looks clean, and the overall construction feels sturdy enough for regular recreational boating use.One thing boat owners should understand is that propellers are not one-size-fits-all. The diameter, pitch, rotation, and spline count all affect performance. A properly matched prop can improve hole shot, cruising efficiency, and engine RPM, while the wrong one can hurt performance or fuel economy. That's why verifying your Yamaha outboard model and existing prop specifications before ordering is so important. The markings on the prop make identification straightforward.What I appreciate most is that this provides an affordable replacement option without sacrificing the features most boaters care about. Whether you're replacing a damaged prop, keeping a spare onboard, or experimenting with a different pitch setup, this appears to be a solid choice. The included hardware is a nice bonus, and the aluminum construction offers a practical balance between durability, weight, and cost.

Unfortunately, not enough. Frustratingly, lack of standards strikes again. They managed to make the hub different.YOUR CONVERSATION WITHOULEME-USJun 8, 2026 6:38 AMWill this also fit a 2025 Merc 40hp ELPT 15 spline, 4 1/4" gearcase outboard?Jun 8, 2026 6:07 PMHi there, Thank you for reaching out! Regrettably, this propeller model is NOT compatible with your 2025 Mercury 40HP ELPT (4 1/4" Gearcase) outboard because its internal hub is designed strictly for Yamaha motors. However, we have the exact right fit for your Mercury engine. You can find the compatible model from the ASIN: B0GQR7R63ZThe propeller does appear well-made, well-finished, and substantial.5 starsWell-made, well-finished, and substantial.
