115 E115MLCRD engine over heated

[comet424]

hi i have this 1984 engine last year it over heated in the water got weeds in it didnt even know from idling the buzzer didnt work so now it dont run heated up

there few issues

one i dont get a spark anymore on an of the cylinders plus the coil packs are oboselete now i hear and i need to know if there replacement ones for it also i got one to work i was testing it with 12 volts but i guess it uses what 3 volts as it was smoking after

and the power packs that power the 4 iginition coils put out voltage from 1 to 3 volts is that right?

also the engine never ran right it wouldnt idle properly and when it did idle warmed up if u put it forward it would always stall unless u did high idle lever and then ppushed forward on the throttle then it wouldnt die so dunno what that is

the temperature probs both melted down

and i did compression tests the one cylinder i get 90psi 2 cylinders i get 60 psi and 1 is 75 psi are they all good or what?


and for parts obsolte what can i do ike the coil packs
