Abstract: A latch system for securing upper and lower cowl sections of an outboard motor. The latch system comprises a catch assembly located at one end of the cowl assembly, and a latch mechanism located at the other end of the assembly. The catch assembly includes a catch block mounted to one of the cowl sections, with a catch slot formed in the catch block. A roller member is mounted to the other of the cowl sections, for engaging the catch slot. The catch slot is formed so as to provide an end wall against which the roller is maintained when the cowl sections are secured together, with the material of the catch block engaging the roller member to prevent relative vertical movement between the cowl sections. A cam block is located at the same end of the cowl assembly as the latch mechanism, and is mounted to one of the cowl sections. A cam follower is mounted to the other of the cowl sections, and engages a cam surface formed on the cam block for facilitating movement of the roller member into the catch slot.
