it's off a 92' chris craft 5.8L (266HP?), i've looked online and saw that there are 3 differant model numbers. are the parts like bearings interchangeable between the 3? i tried finding a model number on the stearndrive it self but couldn't find/have no idea where to look. inside the the engine compartment i found this, OMC Drive System model #987119 serial #T00311289
