This is probably a dumb question considering my boat has an alternator, but is there a stator on 2002 plus - jet drives? Whatever the case, there is a cone shaped serrated piece inside the jet nozzle. Is this piece supposed to spin or stay still on this model? Normally I would think these spin...

What is “the trigger”? And good thoughts on the coil being connected. One is faulty, then that means the other 2 aren’t but would show symptoms from the bad one because connected? In series? I have an 03’ = no stator, I have an alternator. It’s the next generation up before the 250 Opti...

Wouldn’t you think so, now I’m wondering.

I replaced my TPS sensor. Now at 3k RPM and above my boat won’t hit full acceleration because the engine is hopping and skipping. What’s wrong? 240 EFI also. Check my other thread out. I don’t know if this is really the problem. And sorry to hijack your thread

You’ll have to do a lot of work yourself

Get a new battery darn it!

Went for a ride with a buddy and after 3-4K RPMs sounds like engine is skippin a bit. It won’t reach full acceleration. Put the “inline ignition lights” on and found 3 intermittent coils. They didn’t appear to have steady BPMs or pulse tempo at the higher RPM range. First thought is to replace...

Check the damn 20amp yellow fuse inside the square black cover on side of engine

Leave it alone, the oil may be dirty but I bet it’s still in there. Ignore it

Have a 2003 challenger x20, basically same boat as the challenger 2000. All gauges are officially dead. I replaced the RPM gauge with one from an 1800 it appears. Looks almost the same as the Rpm gauge for the 2000/X20, but the back screws on rather than those dumb long skinny bolts. The...

The voltage regulator /rectifier could be bad, but what if the stator/magneto is worn out? These 4techs don’t have alternators, so yeah. Maybe try a fuse!

I’m not exactly sure how an injector would leak, but could be. Could also be an O ring. Agreed. I figure, I could take it apart and look for evidence of what’s leaking. If the evidence is not good enough to point out a specific leaky spot, maybe I could clean everything perfect, put it back...

I have a small amount of fuel in the Intake manifold. Could this be a leaky injector or leaky fuel rail? Or is this normal? I’m the guy on the forum who’s had the high idling surging issue. I’ve traced the problem to here. Could this be causing the over revving problem?

I am looking at replacing these tired gauges with something more modern and cooler as well. Can someone please help me understand the speedo and RPM gauge wiring? What the colors mean and what each wire is doing. I’d like to replace with these cool glow shift gauges. Here is a picture of my...

bang it

Pry it the heck out - knock it out with a bar

Why are thinking about buying one of these? What are the symptoms of your engine? Probably a Merc dealer. Please let me know if you find a good online link. I have a surging high rev issue and this might be the culprit for me as well. I also have a 2003 Merc 240 V6 EFI

You should double check your linkage

What year is this engine. I have 2003. Do I have 2 voltage regulators as well?
