Took it out for the first time and noticed that my battery light would not go off, and I charged my battery before we went out, so I know it wasn't a low battery. I hope it is the inline fuse in the charging system I have read about. I also noticed that randomly my check engine light would come on, could this come on due to the charging problem?? The boat is a 06 model SCIC. With only two people in the boat, it would get up pretty fast, but I do not think it was the ~42 people say this boat will do stock. It would do ~7700 rpm. I am going to check and make sure the engine isn't overfilled with oil and I am going to replace the spark plugs before I take it out next. I had it filled with 87 octane gas, if that matters. Pulling a tube, it lost a lot of its power, and doing curves with the tube killed it. I just had the supercharger rebuild by Jerry at green hulk. I heard recommendations for the solas 13/18, 14/19, and the skat trak swirl, but I do not know what to get. Any help greatly appreciated.

First of all...RUN PREMIUM GAS!

 

Stay away from the 87 octane and any gas with Ethanol if you can too, if not but sure to add the additive for Ethanol

 

I would also think about adding some injector cleaner to the gas, it will help if they are gunked up injectors....I usually run a few bottles in the first runs each year.

 

How does the wear ring look too?

Well I took a look at my impeller and wear ring, and I don't think that either look bad at all, but what do I know. I do not even know the clearance spec. When it lost its power, its not like everyone saying "spinning tires," it was kinda like bogging down. That is what makes me think maybe the guy overfilled it with oil. The guy who had it told me him and his friend just replaced the oil, and as I was talking about the supercharger, checking to make sure it had not failed, he looked at me confused not even knowing it had a supercharger. So he probably has too much in it. I do not know how much overfilling it will kill the motor, but I know it is not good for it. I know around here in NC, all I will find non-ethanol wise is 87. So I guess I will have to run premium with the ethanol additive.

That sounds like gas issue, I had that early this year with old gas, add some injector cleaner and run it close to empty before you add gas, then fresh ethanol additive and injector cleaner.

I am thinking it might be. I went ahead and changed the spark plugs. The old ones had a little rust on the top of them, but the electrodes did not look that bad. I checked that 30A fuse for the charging system, and it was corroded badly. I cleaned it out, and put a new fuse in it. Now it is charging at 12.8V, which is better then before, but I am going to finish troubleshooting the charging system. I went ahead while I was at Oriellys and picked up some Lucas ethanol fuel system cleaner and stabilizer seeing everyone raves about Lucas products. So next time out, I will fill with 93 octane and add the ethanol treatment.
 
I just got done pulling out the multimeter and troubleshooting. Each leg of my stator had under 1 ohm of resistance to each other, and none of them were shorted to ground. at around 4K, the stator was pushing around 45 VAC to the regulator, so it is creating power. Well all that is left to be wrong is the regulator/rectifier.  When running the engine, even at idle, the regulator/rectifier and the wiring coming out of it is HOT. I have seen that a lot of people have problems with the seadoo regulator/rectifiers for the 4tecs, Are they still having problems with them, or is there an aftermarket company that makes a better one for our boats? I looked at my local dealers microfiche, and it calls for a #278001969, which is an updated part, so I am hoping they fixed the reliability problem

The only thing that is not passing due to the specs in the shop manual is when I test ADC at the charging system fuse. I am getting nothing there. So I am still unsure on what is wrong.

Why do you suspect something with the charging system? when it was running bad? regardless if it was charging it should not be low on power until the battery dies?

 

no telling how old that gas was in it....

My 12V low light would come n stay on. I also stuck my voltmeter to the battery and verified it
