The part is already on the boat but these are the numbers on the box.  I'm not sure if any of them represent the 'part number'.  Hope this is helpful.

**Q: Does this work for a 2011 150 HP Optimax?**
A: The one I bought looked exactly the same as the one I had off of my motor, I believe it fit various engine sizes, they wanted 174.00 for one at a local dealer and the boat ran great the whole summer, I enlarged pictures , compared mine, for the price and amazons return policy I kinda rolled the dice ! Hope this helps you out!

    Replacement for msd, holley, etc smart coils.
  

*by J***A on Reviewed in the United States on February 6, 2024*

So far so good. Bought these to replace my oem coils with 300k+miles. Currently have the dwell set at 6.5ms at max effort and 3.5 cruising. Not a ton of miles on them but so far no problems. Just completed Sick Week with them so there's probably 1500 miles and 15- 9 second passes on them. Used with a holley dominator ecu.
