Re: gear oil colour
It could be from contaminated gear oil on the last change possibly depending on how bad it was then. It could also be the brand of oil you are using. Some oils degrade or burn alot quicker then others. Are you using marine grade gear oil or just a 80w90 gear oil? This could play a major part.
