Morning...

Can anyone tell me how to change the lower unit fluids on this engine?

On the lower unit i see the fill screw on the front of the bulb but not sure as to how to guage complete fill? Will it overflow thru weep hole just under capitation plate?

Does anyone have a step by step?}}
 
"There are two drain plugs, on

"There are two drain plugs, one at the bottom and one at the top, take both out, drain the oil and refill from the appropriate squeezy container, from the BOTTOM plug, when oil runs out the top hole you quickly replace the bottom plug.

This is to ensure no air gets trapped in the g/box."

"I have a 140 HP chrysler outboard motor and wish to change the gear lube(lower unit) I see a fill port next to a vent port. There are 2 port
or screws on the bottom, one on the underside
and one on the lower right side of the lower unit.
From what port(hole) does one drain,and or top
up from. Rick"
