Solid Shaft Couplings

The solid half coupling mates with the gearbox output coupling to connect the boat propeller shaft to the gearbox. On solid mounted engines this would be directly connected, however, to reduce vibration and noise transmission, most boat engines are mounted on flexible engine mountings, which means that the boat propeller shafts are first connected to a flexible coupling, such as those which we stock by R and D Marine. The solid propeller shaft coupling are supplied 'Pilot Bored' and need to be machined to exactly suit the boat propeller shaft diameter. Location and drive is usually by means of a key and keyway. The shaft coupling would then be fixed to the shaft with grub screws or with roll pins (screws and pins not supplied). R&D solid shaft couplings are machined from solid steel.
