Maybe I missed this, but you did replace the plugs already, right? That's the first step in diagnosing a 2-stroke. It still sounds like it could be raves not opening. That's right about the RPM they're supposed to activate.
Yes mate new plugs and beautiful colour firing good
Have just got new coil packs delivered and installed
New fuel pump coming in the morning and rave valves have been cleaned and new solenoid installed so they cycle twice
I did notice that the positive wire in the fuel tank to the pump was showing bare wires maybe shorting/earthing out
Still think pump is wrong any clues
Wow, that definitely doesn't look good! I'd certainly fix that, but I don't think there are many minerals in gasoline to conduct current, like there are in water. One explanation for this could be that your pump can't keep up with the high-volume demand of the engine at higher RPM. Maybe it can get enough at low speed, but not WOT. Does it backfire (lean indicator) or sound different when you try to make it go past 5k rpm? Does it die, or rather bog past 5k?
Sounds like I’m pulling the choke on/ bogging down
Had a friend that has seadoo experience ride it and said fuel straight away
Like I said new fuel pump and coil packs tomorrow AUSTRALIA DAY Friday beer and a great going ski I hope
What is the current draw on the pump. The oem pumps were designed to be very low current draw. Most aftermarket pumps have been found to draw more amps than the stock pumps. This can cause issues with the electrical system and battery charging systems. I can't remember what the stock current draw was off the top of my head. Hopefully someone else that remembers can chime in.
Thanks bdesim2 I read that thread and the pump I got today and installed this arvo had every thing needed already installed and a set of filters that fit perfectly
Wet test up the mighty Murray river in the morning
I did the new pump is a LOT quieter than the old one
The pump in previous post is that an original pump?
I’ll let you know how it goes in the morning
Ok pump seems good running much better still a slight miss. Borrowed a pair of plug leads running even better very slight miss seems like a loose wire as on smooth water pushes 50mph but turn or choppy water and still a slight miss very intermittent but nearly there
