I've got a 95 Johnson 25 2strk and on the bottom of the shaft there is the grate for drawing in water and then a few pisser holes that drain water once the motor is pulled from the lake. When hooking up earmuffs w/ hose attachment use a piece of duct tape to seal off the small pisser holes if the earmuff cannot cover these holes or has a bad seal, which is usually the case. As for the milky white lower unit oil, that is a sign of water getting into the oil. This is caused by a few things. 1) Behind the prop there is a gasket (all models) and a trap (some models) which collects fishing line /string/ rope as a protector to the gasket, this may need to be cleared/cleaned. If that is the case the gasket may have been damaged by excess fishing line etc, allowing water to enter into the driveshaft area. 2) the Lower Unit Gasket Seal kit that was mentioned before has failed allowing water to get into the lower unit oil. IF you would like to DIY, check out iboats.com you can purchase a repair manual for about 30 bucks, I did and they are about 200 pages, Brand specific (Merc, Yami, Johns, Etc) cover all models and years, two and four stroke, have tons of pictures with step by step instructions and in my opinion worth every penny. Goodluck! -Matt Also, if you pull the prop, replace the cotter pin with a new one, no need to explain to your fishing partner why he is rowing into shore.
