4.3 Yamaha sterndrive with I believe a delco est distributor. I bought the boat with a cracked block and rebuilt a motor for it. for I have the timing shunt and set the timing to 8 btdc at idle. I disconnected the shunt and reconnected the other plug back in and when I would go to rev the motor it would only go to about 12 degrees. that cant be right can it? I had a old module from a old 350 omc cobra engine and put it in and still the same thing but I don't know if that module was any good or if it would have worked right. any thoughts what the problem could be? im stumped! I was wanting to take it out this weekend but I don't want to if the timing isn't advancing.
