Just an update. Swapped back to the gen iv ignition. Bought new cap rotor and distributor sensor. Cleaned all grounds. Have 12v at the coil and still no spark. Thinking it must be the module but I do have 12v coming out of it at the white/red wire. Kind of stumped and I can’t find another module to test. Ugh!!!

I want to go out tomorrow. Did the water pump. Replaced one side of the exhaust between riser and transom. Have to find a piece for the other side. That’s all that’s holding me up from going out tomorrow. Hoping to find one.

Does anyone here have the procedure for timing this engine? It’s a 454 I believe 330hp. Thunderbolt IV. Don’t know what timing should be at idle and one of my friends said I have to pay careful attention to base timing. Not sure what that means. Right now I have a v8-22 module until I find the v8-24 so that I’m sure will make a difference with timing. Looking for a good starting point so I can take it out and test it

Start with about 10-12 deg at 750 idle. That is base which really is not that important, it is the total that matters most.
you have 22 degrees advance from the module and 10-12 at idle should put total to 32-34 deg total. 10 + 22 = 32 or 12 + 22 = 34
run the motor up to about 4000 rpm and check timing with digital delay timing light fine tune to 32-34 degrees. Now it is set correct.
Go back and check base (750 rpm idle) for future reference to make next time easier. Do NOT readjust the idle timing, it is the TOTAL that is the one you set to.
Congrats on getting it going and how much blood did you loose replacing that raw water pump on that boat?.

Sorry for all the questions. Set it to 10-12 at idle that’s after zero on the balancer right? Also can you run a boat on muffs at 4000 rpms? Just don’t want to screw it up. As far as blood lost a little bit not as much as I thought after seeing where it was
