Hopefully some one might be able to help me with the problem I'm having in my 2008 215 180 Challenger. Started last year after the engine was replaced as a result of, repeated P1520 faults followed by a failed oil pressure regulator and that after Seadoo dealer having had it to sort out the fault issue, saying everything was fine but just add some oil but thats another story. After a maybe 10 hours operation after the new engine was installed, one day out on the sea after a good run the engine would cut out, catch and then cut out again until it would finally stop. If I pulled back the throttle below 4000 rpm to would run fine but accelerate back up again and the same thing happens, pull the throttle back and it goes away and would likely sit there all day like this. I've changed the fuel pump and fuel regulator, both filters and last year I even bought "ouch" a new ecu and had that programmed by the dealer, yes same one as a above! we don't have many options over here, but no good. Over the winter I reverted back to the original ecu and paired it back with the cluster, drained the fuel tank and cleaned it all out, changed the filters again, I've had the injectors refurbished with new filters and o rings, checked the fuel line which was clean. But this year its still doing the same thing. It starts fine runs strong and will likely cruise all day around 4000 revs but if I accelerate up to top speed, which it does really quickly with no cavitation at all, after about 10-20 secs it stalls, catches again and will continue to do so until it stops. As above if I pull back on the throttle it will catch again and run fine. One thing I noticed last week was that after the first time it stalled to a stop, when I started it again and rammed the throttle wide open it stalled on acceleration and then settled down when I pulled the throttle back to return to the dock. No fault alarms. What I did notice last year when this started, was after the engine was replaced the loom was routed incorrectly and was resting on the copper intercooler pipe and on two wires, yellow/brown and black, the insulation had melted off and the wires had rubbed on the copper and lost some strands. The copper was black when I stripped the insulation back and I removed this and crimped the ends back together again. Summer just getting going over here so hoping someone might have some suggestions thatch help me. Many thanks in advance John

Finally found what was causing the problem with my boat above. Loose EMS 5 amp fuse in the fuse block! Seems like the holder has lost its grip over the years and as a result the fuse had worked its way to until it was stopped by the cover. All fine when going slow but at higher speeds the EMS must have been losing its power, causing confusion and shut down. After all that time and money with the dealer last year you would have thought they would have checked the fuse for the EMS. Makes you wonder?

That's crazy. I just got our 2006 challenger 180 and it has a miss at half throttle but hits 7500 rpms easy enough at full throttle but I tested the compression because it won't go over 40mph anyway I'm getting 90 lbs on all three so I'm going to get a better tester to be sure
