need some help with a 1962/63 Merc450. I have a long white controller that belongs to the motor but the controller was taken apart to replace a cable the last owner could not do it. so now i come into the picture, i scavenged another cable for the insert but now i need to know how to put the gears back together and timed also what cable goes to the throttle and what goes to the shifter. could some one help. thanks in advance
