Water In The Gearbox

Whilst draining the oil in the gearbox to get the skeg repaired i noticed the oil was quite emulsified (yellowish brown) so water is getting in somewhere.

Where is the most likely route of water ingress and is it going to be another wallet basher to repair?

Cheers guys

Most likely the output shaft seals .. not a massive job, and dont be tooo worried about the contamination as long as decent gear oil was used .. its designed to cope with some water content to a degree .. but sure enough check the plug seals too as JSP said

That would be my starting point.

I imagined all sorts of horrors when it happened to me. New filler screw washers cured the problem.

IMO try them first, they're only a few pence.

Before you fill it up again, you should have it pressure tested. As I recall, the pressure range is pretty small: just a few psi, but a soapy water shower then should make leaks pretty evident. You could probably rig something up to do it yourself without too much trouble.

Hope it's nothing serious;
