    Question Mercruiser 120 Pulley Crankbolt???

    I have acquired an 82 Galaxy with a Mercruiser 120, 2.5l. The engine was rebuilt and in pieces and I am in the process of rebuilding it. The question I have is that the drawings do not show a crankbolt holding the pulley on. I also do not see one in the manual, nor do I see threads on the crank. I am simply in some disbelief here. Is there no crankbolt? Do I just pound on the pulley and that maintains the seal? Any help is appreciated.
    Thanks.

    Yup it's a press fit only, no bolt on those, pre 68 Chev small blocks were the same way, and I had one fly off a 327 once...

    Ayuh,... I prefer to bridge across the block's front mounting bolts,+ press it on...

    Poundin' it on is hard on the thrust bearing, unless it's sitting flat on the flywheel when yer Beatin' it...
