My old aluminum prop on my bay boat just wasn’t cutting it anymore. I needed something that could handle choppy bay waters and provide better acceleration when pulling wakeboarders. After countless hours researching online forums and talking to other boaters, the Turning Point Propellers Express 4 Blade SS Propeller kept popping up as a top contender.
Unboxing the propeller, the first thing I noticed was the weight and solidity of the stainless steel. The build quality felt immediately superior to my previous aluminum prop; it looked and felt like a serious piece of equipment. The swept cleaver design of the blades was also visually striking, hinting at the performance gains to come.
I considered a few other propellers from brands like Solas and Michigan Wheel. Ultimately, the reviews highlighting the Turning Point Propellers’ exceptional hole shot and its reputation for improved handling in rough water swayed my decision. I was especially keen to see if it could deliver on its promise of increased reverse thrust.
My initial excitement was tempered with a healthy dose of skepticism. Could a propeller really make that much of a difference? I was eager to get it on the water and find out.

First Use Experience
I tested the Turning Point Propellers Express on my 19-foot bay boat in the choppy waters of Galveston Bay. Conditions were far from ideal, with a stiff breeze creating 2-3 foot swells. My typical load included myself, a fishing buddy, and our gear.
The improvement was immediately noticeable. The boat planed much faster than before, even with the significant chop. The handling was also dramatically improved; the boat felt more stable and responsive, especially when turning into the waves.
Installation was straightforward, though I did need a specialized prop wrench. No issues arose during the first few hours of use, and I was already impressed with the upgrade.

After several months of regular use, the Turning Point Propellers Express has proven its worth. There are no signs of significant wear and tear, despite frequent exposure to saltwater. I rinse it with fresh water after each use, and I apply a corrosion inhibitor spray every few weeks.
The propeller continues to deliver consistent performance. I’ve used it for everything from fishing to wakeboarding, and it excels in all scenarios. Compared to my old aluminum prop, the Turning Point Propellers Express offers significantly better acceleration, handling, and overall fuel efficiency.
Maintenance has been minimal. I visually inspect it for any signs of damage or corrosion after each outing, but so far, it’s held up remarkably well. It definitely outperforms my previous aluminum prop in terms of both performance and durability.
