Dear All, <br /><br />I have a 20HP merc, S/No 5731713. <br /><br />The reverse lock system does not work, however, on looking at the system, everything appears to be present but the link rod is not connected to the cam arrangement. The seloc manual is useless for this as it does not seem to cover any part of the exhaust/driveshaft housing system. Does anyone have a clear diagram of the parts that should be present or any suggestions as to how to reconnected the link rod to the cam. The various parts catalogues available on the web show the parts but the pictures are not very clear etc. <br /><br />Any help or suggestions would be appreciated.<br /><br />Stuart
