5.0Lx Merc, turn the key and nothing....

[shute420]

ok, so now i need more direction on what to look for....

1st....i launched today around 11am....started right up, ran find allllll day...cruised here and there, up the river, down the river and all was good.......until we started in towards the marina....

crusing along and i let a jetski pass so i could pull in....he passed, went over his wake, gave it some gas and....dies!!...turned the key and got nothing!...nothing at all...battery was good, everything else worked, but i got nothing when i turned the key....not even a click....trim worked, radio worked...but none of the gauges worked....


short somewhere??....i dont know where to start!....

At the starter make sure everythings connected, battery cable ends(both ends) check the 50A circuit breaker,main engine harness plug, ign fuse(if used), ign switch.

Bt Doc hit it right on the head. I had the same happen to me and it was the main engine harness plug. Mine got bumped by the engine cover and pulled it out a little enough to not get anything. My trim worked but no guages. BK

btw, stupid question but the main engine harness plug is the one that goes into the...?..starter?

Make sure it is in neutral. Happened to me this weekend after I shut her down. Thought it was in neutral but was not. I had to wiggle the lever back and forth.

It`s the big harness plug on the top of the engine,usually mounted on the shift plate that is mounted to the riser.. could be on the left rear of the intake manifiold

Re: 5.0Lx Merc, turn the key and nothing....

the main engine harness assembly looked ok, I did find where 2 of the wires got burnt thru and probably shorted out, but i fixed those and still nothing, I definitely thought that was the issue, the wires were burned right thru......

Do I need to reset the 50A circuit breaker?? If so, I cant seem to push it in.....??

Going to check the starter connections next....

any thoughts?

the positive connection at the starter was really bad looking, not sure if thats enough to shut the motor down...but, its a little corroded and only being held on by a few wires, its not a full connection though....changed the 50a breaker, the old one was corroded and in rough shapeni ugn fues, ign switch seemed ok,....

Just a thought, but have you checked the safety lanyard? If it came slightly dislodged when going over the wake, it will shut the engine down..

Well I changed the connector on the starter from the positive cable from the battery, found a 15A fuse that blew, apparently I didnt look at them good enough the first time, and she started!!.....ran it in the driveway for a little bit and all was ok!!....alright, al seemed ok!..lol
