Dear All, <br /><br />Further to a previous post some time ago, the reverse lock on this merc (S/No 5731713 - 1980/81 20HP) does not function. <br /><br />My question is - how do I get at the part to repair it. <br /><br />Basically, when you move the engine into reverse a cam rotates on the shift shaft in the exhaust housing and pulls down (I think!) on a lever which operates the reverse lock mechanism to clamp to engine to the swivel bracket so that the engine does not ride up when put into reverse. <br /><br />The cam appears to be in place but has become disconnected from the thin metal rod which operates the reverse lock mechanism. I need to get at the cam and rod to see whether I can reconnect them or make a repair, however, I cannot see any way of getting at it without removing the lower leg or other major surgery which I do not want to do. <br /><br />Is there a way to get at the cam without stripping the engine?<br /><br />Any help would be appreciated. <br /><br />Thanks<br /><br />Stuart
