How to identify injectors

[Bazaromcmullen]

Just bought a 94 in february. Anyway to tell if the injectors are stock or if they have been upgraded to marine injectors.

when i bought my marine inj. they looked identical to the stock. no numbers or anything. i guess the only way to tell would be to compare the nozzle and the spring inside to a stock one but that would require a little disassemble. Could be wrong though but thats my take on it.
