I'm getting myself ready to do most of my winterizing for the first time this year and had a quick question so that I don't destroy my outdrive. As far as changing the gear lube... the manual says "Vertical Drive Oil" this would be the fluid that is pumped from the bottom of the outdrive until it seeps from the top vent hole, correct? The manual says to use Fully Synthetic SAE 75W-90 and this is close to what I've seen in all of the video and read in walk throughs.
