Just drained my outdrive oil last night and noticed some light milky color not alot but some. I had the lower unit replaced 2 seasons ago all new bellows. I know the bellows are one of the places to look for water intrusion. Curious were else too look. I removed the cover too take off the fill bolt and it looks like the the seal were the shift linkage has been there a while, is this a place too start. there is some corrosion on the piece that the seal sits in? the bellows look great cant see anything obvious with them. Thanks Erik
