    1981 120 mercruiser broken rocker arm

    I have had brand new engines break a rocker arm. Never had a problem after replacing them. Make sure the stud is not partially pulled out. Use a straight edge or just eyeball the one that had the problem. Check the compression to make sure that a valve did not float and from a bent valve.

    Motor knocking. Mercruiser 3.0 alpha 1

    Earlier inline engines had fiber camshaft gears. Later they went to aluminum which is noisier than the fiber ones. I cannot 100% say that yours is either so the only way would be to pull the cover. Cut off the remaining pan gasket flush with the block and remove the cover to pan gasket...

    85 Mercruiser 3.0 possibly bad coil??

    If you grab the rotor shaft and push it does it make the points open even when the rubbing block is on the flat side of the shaft? If it moves enough that the points open then it is a good time to have the distributor rebuilt or replaced.
