Ambassador Rope Cutter AM15 Blade - Suits 40mm

The Ambassador Rope Cutter AM15 (available in 2-Blade and 3-Blade versions) is built by Ambassador Marine to protect your propeller shaft from entanglement by rope, seaweed and underwater debris. Designed for conventional shaft installations with shaft diameters of 40 mm, 45 mm, 50 mm or the equivalent 1½″ to 2″, this model delivers serious performance in challenging marine conditions.

In Irish waters, with frequent weed, lines or nets, fitting the AM15 gives boat-owners and professionals peace of mind that the propeller is shielded and the vessel remains manoeuvrable. The scissor-action cutter design ensures efficient slicing rather than blunt impacts, reducing stress on the gearbox while maintaining safety.

Whether you’re refitting a cruiser in Galway Bay, maintaining a charter vessel off Kinsale or ensuring a workboat remains operational in the Irish Sea, this Rope Cutter offers a heavy-duty yet serviceable solution. Installation can be carried out with relative ease thanks to the pre-assembled kit, clear instructions, and the ability to match blade count to your propeller
