The J-Prop feathering propeller's key safety feature — pitch reversal by hand underwater without tools — is demonstrated on NV after a gearbox problem prompted the upgrade.0:05 Timo explains that if the gearbox locks in reverse, a crew member can jump in, flip the blade pitch to the opposite side, engage reverse gear, and drive forward.0:20 The pitch is set at 8.1 for NV's engine.3:41 During a trip back to Italy, the crew visited J-Prop's family-run manufacturing workshop, branded as Marine Propeller, where staff trained them on installation and maintenance.0:29 Out of the water during a haul-out, Timo demonstrates adjusting pitch from fully feathered (flat, zero pitch) to the running pitch in a single hand movement with no tools.3:33 He also explains the locking screw system: for high-power engines, two screws block the spring mechanism to fix pitch permanently, while cruising boats can leave the spring active.4:57 The propeller's feathering position reduces drag under sail.3:33 The practical takeaway is that a gearbox stuck in one direction does not strand the boat if the propeller pitch can be manually inverted to compensate.3:53
