Real-World Testing: Putting Solas 2411-138-13 Amita 3 Aluminum 3 Blade Prop Rh 13.75″ Dia. x 13″ Pitch x 13 Spline to the Test
First Use Experience
My initial test for this Solas 2411-138-13 Amita 3 Aluminum 3 Blade Prop Rh 13.75″ Dia. x 13″ Pitch x 13 Spline took place on a brisk, late spring morning on a moderately choppy freshwater lake.

The weather was clear, with light breezes that created some surface chop, conditions that often highlight a propeller’s ability to dig in and maintain grip.
From the moment the throttle was advanced, the difference was palpable. The notorious “hole shot” – that critical moment of initial acceleration – was noticeably sharper. Instead of a slow, drawn-out push, the boat seemed to leap forward with significantly less effort from the engine. This responsiveness was consistent across various throttle inputs, from a gentle nudge to a full blast.
The ease of use was exceptional; mounting the propeller itself was straightforward, following standard marine procedures. There was no learning curve required; it simply bolted on and performed. The most pleasant surprise was how smoothly it handled the moderate chop. Unlike my previous prop, which would sometimes churn and lose grip, this Solas unit maintained its bite, providing a more stable and predictable ride even when the water surface wasn’t perfectly flat.

Over the course of a summer boating season, encompassing dozens of trips for fishing, watersports, and general cruising, the Solas 2411-138-13 Amita 3 Aluminum 3 Blade Prop Rh 13.75″ Dia. x 13″ Pitch x 13 Spline proved to be a remarkably reliable performer. Its ability to handle varying loads, from a solo angler to a full boat of friends and gear, remained consistent. I experienced virtually no loss in performance, even after pushing the boat hard on multiple occasions.
Durability has been impressive. Despite accidental brushes with submerged debris (a common occurrence for me on this particular lake) and the constant stress of high RPM operation, there are no visible cracks or significant deformation on the blades. The aluminum finish, while bearing a few minor cosmetic scuffs, has held up well against corrosion and wear. There’s been no noticeable drop in its ability to grip the water or generate thrust.
Maintenance has been minimal. A quick rinse with freshwater after each outing and an occasional inspection for any lodged debris is all that’s been required. Compared to some cheaper, unbranded propellers that tend to pit or corrode quickly, this Solas model feels built to last. It certainly outperformed a generic replacement I used a few years back, which began to show signs of significant wear within a single season.
