All JohnsonEvinrude outboard engines have at least one, and in most cases two, centering pins installed through the crankcase coverThese pins index into matching holes in the power head block when the crankcase cover is installedThese pins center the crankcase cover on the powerhead blockThe centering pins are taperedThe pins must be carefully checked to determine how they are to be removed from the coverIn most cases the pin is removed by using center punch and tapping the pin towards the carburetor or intake manifold side of the crankcaseWhen removing centering pin, hold the punch securely onto the pin head, then strike the punch good hard forceful blowDO NOT keep beating on the end of the pin, because such action would round the pin head until it would not be possible to drive it out of the coverCentering pins are the first item to be installed in the cover when replacing the crankcase cover
