I've been having problems with my speedometer and tach this season in my 2005 185 with 4.3 engine. The speedometer reads 12-15 mph slow and frequently doesn't even start to register until at 18-20 mph. I've blown out the tube from the gauge end and there does not appear to be any obstruction anywhere in the line, including at the drive unit. I've been using my iPhone as a speedometer which has worked well but would like the gauge to work properly (also I'm scared I'll drop it in the lake!) I've searched the forums but couldn't find info on where to go from here.
The other problem is the tach. It will vary between 3,000 and 4,000 when cruising with no change in speed, throttle, or engine sound, usually reading quite high for our current speed. Eventually it settles down but will still occasionally jump up. Connections are tight on the back of the gauge. I don't know where the engine end is to check that but haven't found any loose connections.
Any recommendations?
Thanks.
