Hi guys,
I am in desperate need of a replacement Thunderbolt IV breaker less electronic timing ignition. Mercruiser v8 7.4 454, 1986 engines.
I had a tune up and my mechanic is having a hard time sourcing the part.
Boat runs great except getting on a plane the port engine starts to miss. Summer is soon going to be over before I get it sorted!
New or used!
Cheers Rob
