2002 Yamaha t9.9 high trust is terrible loud . I ordered some high temp sound proofing and installed it on the inside of the cowling but is still terrible compared to my 2018 f90 . Are the new ones quieter or are they all loud . I’m thinking about selling it and ordering a new one for next year. Also wondering if the new ones are any lighter then a early 2000 model.
