[mrapala]

Hey guys need some help what is the correct setting on the back of tach for 1999 150 two stroke EFI changing out too newer tachs

Gee, the tach manufacturer should have a listing of the settings. Normally Merc uses 12P or 6C, whichever you have.

I did find out that it is a 12 p was just wanting to make sure that the 6c setting would work thanks for the reply
