if you have the HVS type dist(flat cap) ,there is a marked position

Usually the ecm controls the timing? all you do is install the rotor in its a marked position and the computer does the rest Need the full engine number to determine the correct manual number This is free to read https://www.scribd.com/doc/124300386/Mercruiser-5-7L-MEFI-5-Service-Manual

your overthinking it if carb`d then sprat thru the carb till it stalls, TBI,EFI you use a remote tank with a winter mix to fog it

get the GM version , grind off the rivets, install the brackets on the new coil and bolt brackets in place. In time the rust will expand the coil internally and cause it to fail ACDelco GM Original Equipment Ignition Coil Kit 19418995

try looking where the block drain is , that where mercruiser put theirs, they T into the drain port

Well here`s one I could not figure out.Gm v6 mechanical pump Occasionally after about a 1 hour run I would be leaving black smoke and running rough before it would flood out. Rebuilt the Rochester carb completely worked for about an hour and did the same thing. OK ,figured the carb was shot...

How did you drain the system ? IF a single point system my guess the engine block did not drain completely. You can verify by unhooking the block drains and probing the fitting with a nail or screw..Almost every customer of mine with that system it usually is the port side .

looks like it was the incorrect impeller to begin with
