1973 65 hp evinrude triumph model

[WayneV]

I recently bought a used boat. The engine now has no spark, went to use boat and wouldn't fire. Took boat to dealer,they checked for spark,only had spark only at #3 plug,he energized other coils and now spark at all coils,now engine runs fine. He said it could be power pack,$120.or stator/triger assembly $300.and to replace both $500.parts/labour with no gaurantee it is fixed.I am a retired auto mechanic, I took it to dealer for sake of conveince. What manual do I specifically need to diagnois and repair problem and what could be the likely problem or cause? I'm thinking intermitent open curcuit in power pack.

I bought one of these engines and had the same problem. It was the trigger assembly.I found this by checking resistance. I took 2 bad assemblies and made 1 the individual triggers are replaceable but i don't think you can buy them.
