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

Do you know how long the oil had been in there?

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.
