I'm running a 2012 Glastron GT205 w/ the 4.3 I/O motor.
I noticed Monday while I was out on the water, my speedometer was not working. I've already ran a small drill bit with my fingers through the hole on the bottom of the lower unit, I disconnected the tube from the lower unit and blew (with my mouth) into the hole. I was able to feel the air pass through, so I know there is not blockage there.
any ideas what I should check next? is there a sensor that the water pressure is measured at, or does the rubber host go straight from the lower unit to the gauge? if that's the case, I guess it could be a blockage within that part, and I'll start from the gauge and blow some compressed air.
appreciate the help.
