150hp 4 stroke squealing noise

[jfunk]

Hi. New to forum and I need help. I have a 2009 yamaha 150hp 4 stroke outboard. I love the motor but recently it started to have a squealing noise when I first start the motor. It does not happen every time. Sometimes starts fine. After squeal stops, it sounds and runs fine. New water pump last year and just did all the fluid changes. Everything look good. Any help??? Thanks

Possible drive shaft bushing in the exhaust housing. Drop the lower and use a good water proof grease. You will see it.
