Shift into 1st gear and speed up engine to prevent stalling if water hits it. Keep engine speed above 950
Enter water slowly.
Keep engine above 950 rpm. Drive 3 to 4 mph (4.8 to 6.4 km/h) to prevent making a bow wave.
If vehicle is completely submerged to a point where water enters engine compartment, keep engine speed
up to prevent water from entering engine. Move vehicle out of water immediately and drain engine
compartment by operating drain valve lever (see para. 2-1g(2)). If engine stalls while completely
submerged, have vehicle towed out. Apply temporary preservation as outlined in Appendix F. Notify unit
If you have to stop while engine is under water, brake vehicle and shift to N. Keep engine at 950 to 1000 rpm. To
move again, shift to 1st and go forward slowly at 3 to 4 mph (4.8 to 6.4 km/h). Keep engine above 950 rpm.
