It is simple to install and can be adjusted to the required position on the shaft. This clamp on shaft coupling is bored only (no keyway) and is secured to the boat propeller shaft with the clamp bolts supplied.\u003c\/p\u003e\u003cp\u003eTypical applications include:\u003c\/p\u003e\u003cp\u003e4\" nominal gearbox flanges of Yanmar KBW10 \u0026amp;
