2010 Seadoo Speedster 150 (155hp) sporadic starting and stopping issues

[bakersboas]

Recently my Seadoo has developed some starting and random shut down issues. I have done hours of internet searches but I still need some help. So far I have replaced the DESS post with no luck on fixing the issue. Also, I have checked and cleaned the ground wires.

My boat will start fine out of water but will just randomly shut down while driving. Most of the time, I will reattach the key and the boat will start but it takes multiple attempts. Sometimes I get the 2 beeps and it will start right away, other times it takes up to 10-15 minutes of reattaching the key before I get the 2 beeps to start the boat.

At this point, I’m seeking advice on what to do next? Could it be that I need to have the key’s reprogrammed? Could it be that the red wires on the solenoid are connected to the wrong terminal? Thoughts? Here is a pic of the solenoid wires.

The lanyard could be your issue,,,it has a magnet in it,,,that closes the circuit in the dess post that has a tiny glass reed switch,,,you can do a resistance test on the key,,,I believe if the resistance is more than 10 ohms.,the key can fail.,,I dont believe it can be reprogrammed,,,so you would need a new key,,,and have the key programmed to your ecu.

Thanks for the reply. I do have 2 keys, both are doing the same thing. It seems odd that both would go bad at the exact same time though, doesn’t it?

I have the 07 Speedster 155 that had the same problem. I have the Candoo scanner and no codes would set. It would just shut off sometimes and usually, I say usually because a few times it would take 20-30 minutes, start right back up. I was on the Candoo forums and the consensus was lanyard, DESS post or VCM, in that order. Well I changed all three and still had a problem. Ended up being the ECM. Before I changed any part I pulled the wiring harness and cleaned and greased every connector, did not help. Been 2 years on a new ECM, runs great.

Agreed,,,2 lanyards not working,,,is not reasonable.

I'm having kind of the same problem right now. My Challenger 180 will start and drive without any problem. But the moment I shut it down, it will take me 5 to 10 mins playing with the shifter to get to start and it will start on forward or reverse for some reason which makes the boat super unsafe. I have been reading a lot about it and can't see to think or find what could be the problem.
