British Seagull Outboard Model Identification

To identify your Seagull outboard motor, you can visit the Seagull Engine Numbers table below and search for your I.D. letters, which are the first set of letters in the sequence.

This will give you the type of British Seagull, and in some early cases, the number will give you a rough guide to the year.

Alternatively, you can use this British Seagull Outboard Motor Identification submission form by entering your engines ID numbers stamped below the crankcase as seen here showing FP2050G8 - enter with no spaces.

About: Marston / British Seagull Outboards

British Seagull was the design of John Marston's engineers at the Sunbeam Motorcycle Co. as they began to diversify into the marine market beginning in 1931 under the name Marston Seagull. Later John Way-hope and Bill Pinniger took over and by 1938 they moved to Poole Dorset, continuing production then as British Seagull into the mid 1990's.

In its heyday of the 1970s, British Seagull was selling over 80,000 motors a year – small, affordable, bullet-proof outboards for pushing the tender, dinghy or pocket cruiser along when the wind settled down.

The Model 170 was released in 1982 followed by the Model 125, and then the QB Series of British Seagull outboards where introduced at the 1987 London Boat Show with the 6hp Kingfisher, followed by the 5hp Osprey and the 4hp Curlew - offering the latest in 2-stroke technology. 

Remaining parts-and-products inventory was purchased by John Williams in 1996. However, its successor, Sheridan Marine, as well as others still supply parts.
