1992 4.3 mercruiser Alpha one Gen II. Any tips on changeing rotor under dist. cap? This one seems to be stuck good. Dont want to damage dist.
 
This is the way to remove the rotor.

this is a rough drawing.

Use very good screw drivers with heavy duty tangs must be used. also it is reccomended to make the U shaped pieces to protect the distributor housing from damage. You must apply as equal of pressure to both screw drives as possible. If this does not work then carefully breaking of the rotor can be done, CAREFULLY!!!
 
Also you could heat it up with a hair dryer that would help some and should not present a fire hazard if used correctly. Just dont heat the sensor in the bottom of the distributor or you will be replacing that also........

NOTE: using any heat device in a marine engine bay EXTREME CAUTION MUST BE USED!!!!!!
