Hello,
1st time here and posting but i have a concern that i hope someone might be able to help with and would be much appreciated.. I have a 2004 nitro bass boat with a 90 hp outboard, I bought the boat new...the issue is #2 cyl keeps blowing the module/coil. no other cyl ever affected.......I have spent many years as a auto mechanic so am not a newbi when it comes to mechanical stuff......this has been going on since the 1st year of having the boat......i have went thur and removed all grounds and sanded down due to paint over grounds...at 1st thought it fixed the concern, but yesterday it did it again......this will be the 5th module i have had to buy for this concern.(which isn't cheap)
There is no special times it happens, as it has done this under full power, and other times at very slow speeds........once it drops that module..its done...most times, motor runs great for days, or even weeks to afew months.
I have checked, double checked all wiring to that module, all test out good.
i have looked at a shop book and appears all modules....(3) run off pick-ups of flywheel, but they are all wired together, and #2 is the only cly ever affected. Has anyone ever heard of this or had this issue........any helpful ideas would be great as i'm pulling my hair out...............Thank you in advance
