A friend has a 2003 50 horse 4 stroke Yamaha and told me that there is milky leakage from the lower end.... I haven't been over there yet, but I assume it's the prop shaft seals/o-rings. I've never worked on a Yamaha lower end ( and have very little experience on my Johnson) and don't have a manual, so I was wondering how big of a deal is it to change out the seal ??? Any special tools needed ? Tricks of the trade ?? Thanks !
