2007 F115 Speedometer Pitot tube

My commandlink speedo just started giving me false readings. I assume that the pitot tube or inlet is clogged.
I want to take some leader material/mono and try unclogging the inlet, but I'm not sure where the inlet is.

Can somebody post a picture or describe exactly where the inlet is on a F115?

My boat is in the water, docked at the marina, so I'm going to try an unclog while hanging over the transom. I can't feel where the hole is. Can anybody help?

Thanks...

Don't have a picture but it's a small hole in front edge of gearcase below the waterline.
