I get a squealing noise from my 2015 50HP 4 stroke. sounds like car tires braking.
Any idea what causes it ? Here is the actual noise : http://www.youtube.com/watch?v=DzAzqAJAS6Q&feature=youtu.be&t=119

Take it back to the installing dealer for warranty work. You paid for it.

this turned out to be a missing flowtorq hub in the prop (and wrong prop)
