70s johnson 85hp wiring diagram

[casi77]

im looking for the wiring diagram of a 70s motor, v4 85hp johnson. my manual covers up to 60hp and not V motors.
can someone send it to me please or let me know where i can find it online?

i just bought the motor.. i have a problem with spark (very weak and no spark), coil is getting very hot and believe it is filled with oil as it says on the coil itself and also says that it needs a external diode. It gets hot and on top of the coil its kinda bubbling (sizzling) around the top cover. i see a white rectangular diode looking piece with two male connectors right beside the coil but its not hooked up to anything. coil has two wires which are hooked up directly to the wiring block on top of it, but i need to trace where exactly its connected too. belive the weak and no spark problem is related to this coil!?

Yes, that model number indicates that the engine is indeed a 1970 85hp Johnson.

However, that engine originally incorporates a Battery Capacitance Discharge type ignition pulsepack (solid state ignition). I can only assume that someone has converted or attempted to covert it to automotive type ignition by what I've read above.
