C8.3 Commercial Marine and Ind [...] Cold Weather Starting Section 1 - Operating Instructions Page 1-15 In cold weather, the WAIT-TO-START lamp will stay on longer. If ambient temperature is below 16° C [60° F], fully depress the throttle after engaging the stater. Full throttle on the VE pump makes sure there is sufficient start fuel delivery and helps keep the engine operating once started. The in-line pumps with RQV and RQV-K governors require full throttle position and hold the rack in the start fuel position. The throttle must be depressed after engaging the starter to allow the shutoff lever to move to the run position before moving the throttle.
