Just got a 2001 viper coral and in a page out of "Don't touch that!", I saw this little hose seemingly coming out of my lower unit. I touched it to see what it was and it snapped like a twig! What did I break?
2001 Merc 200 EFI
To me in the pic it appears the two hoses are a different size, like maybe the previous owner had the smaller one stuck inside the larger one - shade tree mechanic. Might be wrong, never seen a speedo with that grommet looking thing.
