So I bought a boat last year that has a 2007 225 Yamaha 4 stroke. I did not hit anything with the prop that would cause my issue. I winterized my motor last year myself, when I drained the lower unit it was the color is should be (clear looking like molasses). I replaced that with new lube to sit in over the winter like you should. I decided to take my boat out to the river yesterday and when I was putting my boat in the garage last night I noticed by my top lower unit screw( where you put the oil) there was a little milky color coming out by the screw. I freaked out cause I know you don't want any type of water in the lower unit. So I ran two the dealer bought some new lube came home and drained the lower unit and it was a Carmel like color. When I took the screws of both sealers were on the screws. I immediately changed lube and righted back up.

My questions is what caused this to happen? Do I need to worry about it this? Could it possible be from the screw not being tight enough? Why was the color  Carmel looking?

Any feedback would be much appreciated I want to resolve this problem before I  have more serious-issues down the road.[/QUOTE]
