Oil Seal 09282-17009

Function and Technical Context

The oil seal 09282-17009 is a sealing component belonging to the lubrication system of the outboard engine, whose mission is to prevent oil from the crankshaft or transmission shaft from escaping toward the exterior of the engine block. Manufactured with exact dimensions of 17 x 28 x 6 mm, this seal operates under demanding conditions of temperature and continuous friction, maintaining the necessary tightness so that lubrication pressure is preserved at appropriate levels. Its correct operation is decisive in Suzuki engines of the DF and DT series, as well as in Johnson and Evinrude engines of the E25, E30, E40, E50, J25, J30, J40 and J50 ranges, where it acts as a barrier between rotating components and the external environment. If this seal fails, the engine may suffer progressive oil loss, contamination of other areas of the powerplant group and, in advanced cases, severe damage due to insufficient lubrication in the bearings and moving parts of the assembly.

When to Replace this Component?

The most common symptoms of a worn oil seal are the appearance of oil stains or streaks in the lower area of the engine, smell of burnt oil from contact with hot surfaces and a progressive drop in oil level with no apparent cause of internal consumption. This type of component should be inspected during each seasonal service and replaced as soon as any indication of leakage or softening of the sealing lip is detected; in engines with many operating hours or stored for prolonged periods, the elastomer tends to harden and lose its sealing capacity, so preventive replacement during annual maintenance prevents costly breakdowns and unexpected immobilizations while underway.
