New Yamaha 9.9 vs old noise level

Postby doubledutch » Sat Oct 07, 2017 6:05 pm

The Yamaha web site seems to suggest that the new model 9.9 has improvements that affect the noise level. Did those of you who have installed the newer engines notice a difference?

Most definitely. Unfortunately the biggest difference is at idle, can barely tell they’re running. At full throttle they’re still louder than I’d like.

I tend to motor with engine at 3600 rpm. Is there a noticable difference at this point?

Yes. But only because I have a '98 and a 2013 on either side.
