I would question the details of the advert regarding the engine as we have a Contessa of this age at our marina with its original engine and it is not 18HP It is an elderly Yanmar single cylinder Horizontal.
18HP is an unusual rating for 1973. It could be a Yanmar 20 GM from the 80s/90s or a Volvo 2002 80's . I would check this.
Very easy to check, there is a picture of the 2 cylinder, 18hp Sabb in the advert
