Yamaha 150 Txrb 2003 Exhaust issue

[Daniel.Meystrik]

I have a 2003 150 Txrb and it started smoking alot. I just tested it with ears feeding water to the lower unit and it was smoking alot again but I noticed that no smoke, very little, was coming from the upper exhaust holes and the air being exhausted was cool. I also notice a bit of oil conming out. Looking at the forums I found a lot of talk about corrosion and extertior oil pump overflowing the mail on the engine. Anybody have this experience with this? Engine starts up everytime and is reliable. I did replace head gaskets a few years back and corrosion was present.
