This British Seagull® SAE140 Outboard engine gear box oil is suitable for all British Seagull engines fitted with non-sealed gearboxes.
This classic oil for British Seagull Outboard engines lubricates the gearbox parts and must be topped up every 15 hours running. Once a season, preferably when laying up, the box should be completely drained and refilled.
This British Seagull gearbox is not fitted with ball bearings, so it can be, and is actually designed to accommodate some water and a water/oil emulsion is quite acceptable. Under no circumstances must grease be used in the gearbox.
It is important to use the correct gear oil in the right gearbox and to the specified level. If you are unsure please contact British Seagull Outboards on 01491 652755.
