    Default Yamaha 90hp Head Torque Requirement?

    I would like to check the torque of my Yamaha 90 hp head bolts but do not know what the torque pounds requirement is? Can anyone provide that to me? Thanks in advance.

    Default Re: Yamaha 90hp Head Torque Requirement?

    144 inch/lbs. or 12 ft./lbs. I do 10ft./lbs. then go to 12ft./lbs. I put a little oil on the threads when installing.
