Surfriding Stumped-ski will not start any ideas?

[peterlocal22]

Ski has been having problems for the last month.
It all started when the Bendix exploded.
I put in a new oem Bendix as well as a new stator because there was metal all over the place in the flywheel area.
Ski started but wasn't running great.
Cleaned carbs out and found some debri in the fuel filter as well as
Removed the e box and hooked up the epic cdi to computer. The curve was all messed up so i fixed the curve.
Ski ran great for five minutes until I hit my first wave and then it shut down again. Couldn't get it started.
Went through it again and found the spark was very light and sporadic. Found out the rectifier and cdi were shot.
Replaced both. Spark is good but ski will still not start. Removed black and white wires from start stop switch and still the motor will not start. Just turns over and over and over.
Put some fuel into carbs- still nothing. Changed out the whole start stop switch with a brand new one- still nothing.
Battery has 12.6 or so volts
I'm stumped? Anyone have any other thoughts before I totally freak out and smash this boat.

Compression?

Compression or timing. As a quick check, put your thumb over each plug hole and crank. If your thumb isn't getting blown off each hole, you got low enough compression to give you starting issues. If that's not it, take the flywheel off and inspect the woodruff key

my comp gauge is broke so i tried the thumb test and both cylinders seem to be the same and both seem to be good

You had salt water in your ebox? Check every wire connector in there, my guess is a bad wire end or ground. Also like matt said, being you had FW off wouldnt hurt to check the key again.

 

[peterlocal22]

Ill check the key, all the wires in the ebox have been replaced

 

[shawn_NJ]

I would test every wire on the ski still. Its normally the simpliest thing that will drive you nuts. I had a wire that had a nick in the jacket smaller then a grain of pepper. Salt got in there and turned the whole thing green, althought the wire looked perfect.

im with Matt E on it being the flywheel key. I couldnt start mine for the life of me this past summer. had great compression, a lot of fuel, spark, and nothing. the flywheel key was sheared. it was totally out of timing.

 

[ntrsspray]

You could have spark and the timing still off. Spark only matters if its happening at the right time. Pull the FW

if all else fails.....try a known good cdi. I had similar symptoms (no start after first ride). I went through all my wiring etc....couldn't find anything out of tolerance. Left it alone and it started up the next day. Rode again and it wouldn't not restart after first ride. Swapped in stock CDI cranked right up. I suspect my JSS coil wires might be the problem. The epic (since it's digital) needs everything to be PERFECT, it is super finicky. I'm thinking once the wires get a bit of water on them they are arcing and causing interference that the epic doesn't like...........swapping my JSS coil out for a 760 coil. Nuff about my issues. hope you get this figured out.

its a brand new epic, with all new wiring in the ebox. spark looks great.
checked the key in the flywheel and its working correctly,
i did notice that when im cranking the motor the carbs may not be sucking in any fuel because the fuel filter on the fuel line doesnt seem to be flowing correctly

But if you pour some premix down the carbs it still doesnt fire up?

 

[peterlocal22]

stupid battery died, ill charge it and give it a run

Status?

 

[peterlocal22]

ski finally started after i cranked it for a while with the throttle wide open. air issue?

 

[SkiDiggity]

could be vacuum problem at the carb i had issues with that ski did not want to start but when it would it wouldn't run at all until it desieled on me and took off like a screaming banshee on the trailer. try replacing the carb gaskets or if you can get it fired spray crab cleaner around the base of the carb if it will continue running as you spray then you have a vacuum leak. Also i know this may sound dumb but i had this happen to me, check where the fuel lines go to the carb you could have a small slit in the line causing it to suck air.

hope this helps.

got the ski started, found another area on the start stop switch where the heat burnt through the coating on the wires and they were all touching. Seems to be much better now. Im going for a test run today. always something with these toys.
ill report back later.

 

[SkiDiggity]

cool glad to hear that was the only problem!!

 

[peterlocal22]

ski ran the balls today, thanks everyone for your help

Sweet!
