Solas 19.3x15 Aluminum Prop for MerCruiser Bravo Two Sterndrive

This Solas aluminum propeller (part number 1611-193-15) is specifically designed for MerCruiser Bravo Two sterndrives – the marine outdrive used on high-torque engines and heavy boats. The propeller features 3 blades and an impressive 19.3" diameter, making it one of the largest in its class. It is intended as a replacement for the original aluminum props on Bravo Two drives and is equivalent to Mercury’s OEM part #48-18610A40. With the Solas Bravo 2 prop, you get excellent quality and performance, often at a more affordable price point compared to OEM Mercury propellers.

The large diameter and blade area of this prop make it extremely effective at generating thrust. The blades grab significantly more water each rotation, which is crucial for boats with higher displacement or those carrying heavy loads. The 15" pitch is carefully chosen so that the engine can still reach its recommended RPM even under substantial load – the prop won’t overburden the motor, but instead allows it to operate in the optimal power band. The result is strong pulling power, superb low-speed control, and reliable cruising performance for bigger vessels such as cruising yachts, large sport-fishing boats, or utility workboats.

Solas employs an advanced squeeze casting process to manufacture this propeller. This process yields a denser and stronger aluminum structure, making the blades more resistant to flexing and impacts compared to traditional die-cast props. Each blade is precisely crafted to minimize vibration and provide stable, smooth operation. The propeller is coated with a multi-layer powder paint finish that shields the aluminum from saltwater and corrosion. This is especially important for boats that stay in the water long-term – the Solas prop will resist rust and electrolysis, maintaining its smooth surface and structural integrity.

Installing the Solas 19.3x15 on a Bravo Two drive is straightforward, just like mounting the original prop. It features a 19-tooth spline hub and right-hand rotation, matching the standard MerCruiser Bravo 2 output shaft specification. Simply use the appropriate hub kit or nut (if not a one-piece hub) and torque to MerCruiser’s recommendations. Once in place, you’ll immediately notice improvements in thrust and maneuverability – your boat will climb out of the hole more easily (accelerate from standstill faster) and hold course even in challenging conditions like heavy seas or headwinds.

Recommended Uses and Applications:

• Perfect for heavy vessels such as large cruisers, custom sport-fishing boats, or pontoon houseboats equipped with Bravo Two drives – this prop provides the thrust needed to propel 24+ ft boats and beyond
• Suitable for commercial and work boats (e.g., pilot boats, utility barges) where dependable propulsion at low and mid speeds is critical – the huge diameter ensures maneuverability under hefty loads
• Allows heavy boats to plane more readily – especially for craft carrying significant weight or multiple passengers, this prop helps the engine spin up to RPM and lift the bow more effectively
• An excellent alternative to stainless steel Bravo II props: the Solas aluminum prop offers strong performance and a lower cost, while also being easier to repair or replace if impacted, all without major sacrifices in durability or thrust
