Need a little help (superjet)

[turbofab]

Ok well it all started when my started solenoid random got stuck on causing the motor to turn over. this is all happening in my garage on my trailor. of coarse hitting the stop button doesnt do anything so i find a 10mm and unhook the battery, the ski has been turning over for about 45 seconds before i un hook the batt. so i buy a new solenoid, new ebox gasket ( needed one) take it out to the lake and now it turns over for a little bit and then does a compression stroke out of the exhaust causing water to splash everywhere. after about two more of those it starts and i can ride and everything feels normal, but when i shut it off it does it all over again. Now this ish blow i went from a ski that would start the first press of the start button to one that takes a while. i have no clue what it is. please help.

Weak battery Maybe , bad ground check resistance. i run 9lbs battery and mine barrery cranks now after i added more compression.

solenoids get stuck usually from trying to start the ski with a weak battery.

The solenoid isnt the issue now i fixed it. the issue is how after turning over it shoots a compression stroke out the exhaust almost as if the stator timing is off

Backfire.!!!!

Kinda yes but thru the exhaust not intake

thats the typical symptom of a bad MSD enhancer.

if they get wet, they die.

if they stay dry, they live for a LONG time.

take the enhancer out, and set it on top of something warm, window sill, TV, somewhere warm and dry for a week or more, it will likely work again.

Really thats not what i wanted to hear, WTF

Did you find water in the e-box at any time ? also threads say to put silicon around the msd rev limiter adjusting screw after you set it to help keep water/moisture out of enhancer...

Thanks james and yes there was water in there at one point, but i dont think it was for long, i got a new ebox gasket and its staying dry.
