Hello Mariah owners, I'm new here
 

New at the site, glad I found other Mariah owners. Love my boat. Have a 2000 Shabah 202, 5.0L I/O. I am having problems with my Tach & Speedometer this year. The only thing I did different this year was install a new Sony stereo to replace my old Sony cassette. Plugs were the same, so no rewiring or adding new wires. Don't know if this has anything to do with why my Tach and Speedometer are not working or not. Has anyone else had this problem, and what did you do. Any recommendations from anyone, would be appreciated. Thanks
