I have a 2007 skeeter with a 90 yamaha on it, one day the speedo just quit. I read some posts here with same problem but did not see an answer that would help my situation. My inlet tube is in the foot of motor, tube is clogged inside the foot. I have a small rectangle hole in casing to allow water, this IS open. Took a flashlight and looked in the opening and seen the tube coming from the top, but not seeing the exact opening for the pitot itself. Undid the tube right above foot where it comes out of casing and blew 100 psi air back thru but nothing coming out, all its doing is expanding the tubing. Any ideas would be greatly appreciated!!!!
