What is with these 5EC's? I have had issues with mine from the day I purchased my 280 new in 07'...Anyway, my latest issue is a LOC code....When at the shop with a hose connected for cooling it runs flawlessly...Once in the water it starts and runs 4-5 sec, then ****s off with an LOC code. I have rulled out a bad impellor as the flow is fine at the shop with a hose connected. Further, I have checked for positive water delivery from the seacock. I have "skirted" this issue before by disconnecting the temp sensor lead and it runs fine...But that's not a good answer in the long run (and will always end in writing a bigger check). Any Idea's?
