Call Yamaha at 866-894-1626. They are very helpful. Sure they can tell you
which hole to clear.

Help, my boat speedometer has quit working. I can keep track of my
speed with my GPS, but I'd like to get the speedometer to work. It is
operated by a pitot tube. I have checked behind the instrument panel
and everything appears to be fine. I believe that the pitot tube is
plugged somewhere, but I don't know where to look. I have followed
the tube to my outboard motor, a Yamaha F115, but I don't know which
opening is for the tube. Any suggestions short of taking the motor
apart?
