thunderbolt ignition, is it a lV or a V

[onebighead]

I have a 1998 mercruiser 305 chevy, ser L619326, and I still can't tell which system I have. I know I have the mefi 3, with tbi, but the distributor has nothing mounted on it. The mefi 3 box is mounted on the riser. I have the two wires coming out of the distributor. The references i have looked at show the same dist. on TBIV and V. No problems but ready for timing. thanks (the manual #24 does not specifically id.)

It's V, all the IV's ended in 96.
The reason nothing is on it is because the ECM does all the work. No need for additional modules.
