Patent attributes
A seal member seals a gap between upper and lower cover members of an engine cover of an outboard motor. The seal member includes a supporting portion and a sealing portion integral with the supporting portion. The supporting portion has such a high spring modulus that the supporting portion is not plastically deformed with a load is applied to the supporting portion when the upper cover member is locked to the lower cover member. The sealing portion is hollow and has such a small spring modulus that the sealing portion can readily flex into close contact with the upper and lower cover members so as to provide an improved seal between the upper and lower cover members.
