ok, drive oil is leaking into lake when prop is in motion. its also leaking into bottom of engine compartment. milky white substance at the bottom of drive oil reservoir, im assuming its water. so, if water is getting in the line and oil is getting out, im guessing i need to change a bunch of seals. i need to know step by step how to do this and what tools i will need because i have no clue where to start. any suggestions or instructions would be greatly appreciated.
