Mariner 30hp Oil injection, can't find oil tank ?

[Craig Williams]

I have just bought a Mariner 30hp, which I believe is a 89 model.<br /><br />Model 30 ELO, Ser 689 L 421046<br /><br />It has oil injected on the side of the cowl but I can't find an oil tank anywhere ? I can't see any evidence that there has been one there either ?<br />Maybe I am missing something, or it is somewhere & I haven't seen it. Can any one help and also confirm the year model.
