Hello everyone

Yikes.  Hate to hear that.  I have a 135HO with about 110 hours.  It has been awesome except for the odd time during hot/sunny/no breeze days when the 'hot air sensor' will sound after about 4 hours of trolling.

 

Hope one of the forum experts can give you some direction.  However, a knock is something that I am sure they will tell you to get your friend to get that engine into a 'good' Evinrude Dealer to diagnose...

Can't really diagnose a sound on a computer screen and without examining the engine.

Unusual sounds should not be ignored. Your friend should have his motor checked out right away by his Evinrude dealer. The motor is probably covered by warranty if it is used as recreational.
