British Seagull® Outboard Drive Shafts link the bottom of the crankshaft at the top of the engine, to the top of the bevel pinion at the bottom of the engine, transferring power from the power head to the gearbox.
The British Seagull drive shaft sits inside the British Seagull Outboard Drive Shaft Casing Tube and is constructed of hardened box steel.
There are several different lengths for the British Seagull Outboard range and the length must match the one the engine was manufactured with.
