2014 LSV 247 with LS3 engine code for cylinder 7

Recommended Posts


Ju. st bought boat last week, ran great for 2 hours now won't go over 10 mph. Has engine code for 655597. I have 2 questions, does this system have a OBD2 connector for a scan tool? (i just upgraded my SNAPON scanner last week), and the next question is, are the coil packs a (marine specific) coil pack? any input would be greatly appreciated!!!

You would need a OBD-M CAN diagnostic tool to connect to your ECM.  The most commonly used one, and what Indmar and Marine Power recommends, is a Rinda Diacom kit which allows a Windows laptop to connect to your engine.



Coil packs for the LS3 should be ACDelco parts, but you have to find one that is is same as what is on you motor.  This is the one used on Indmar engines.


I bet yours has an ACDelco number stamped right on it.

Did you narrowed down your running issue to a failed coil pack, or is it a guess?

I’m just brainstorming before I start digging into it. And I’ll check out that link you sent. Thanks!
