I have a 2001 Sanger V210 with the 330hp black scorpion engine. The boat died as I was idling and would crank but not start. the next day it fired right up and ran perfectly for a few hours. It then died again and I was barely able to get it going after about twenty minutes of messing around. It now just cranks and will not start at all. I have established that there is no spark. I have replaced the coil and complete distributor including ignition module. I have tested all fuses and grounds and they all check out good. And I have disconnected the tach wire just in case it was shorting internally. I have power going to the coil and a constant 12V on the lead that goes from coil to distributor when the key is on, but it isn't spiking voltage to give me a spark. I have tested everything over and over and tried multiple coils just in case and nothing seems to get me spark. I am at a loss as to where to even check next.

Here is my distributor and coil. It's electronic ignition with the module in the distributor
