I have a new 05 200hp VMAX HPDI on a 2007 SL210 Skeeter F&S. Took it to Lake Kissimmee FL last week. Speedo quit working on the second day out. Got the skeg in the mud. Found a stick in the hole in the front of the LU, just above the skeg, where it rounds out for the prop shaft. I "assumed" this was the inlet for the speedo. Pulled the stick out and the speedo still doesn't work. No speedo pickup on the boat... any ideas?
