Compatibility and Fitment
This prop suits gearcases built for 14¼” diameter props with 19″ pitch. Because the 4-blade format offers more blade area, it benefits boats carrying heavier loads or operating in rougher water. To achieve a secure fit, install the appropriate hub kit for your engine’s spline and shaft.
Compliance and Safety
Installers must follow engine manufacturer specifications for clearance, torque, and propeller matching. Balanced blades reduce vibration and improve safety, so check alignment before use. Always disconnect the ignition before handling propellers and wear protective gear during installation.
Marine Applications
The BLA Prop Alum LE-1419 4-Blade performs well on recreational boats, sterndrives, and outboards that need stronger mid-range thrust. It also helps vessels that run in chop or require added control during manoeuvring. Consequently, many boaters choose a 4-blade prop when they want smooth performance under varied conditions.
