Hi : first let me express my regret over your purchase of two sc , 2015 Sea Doos
I made my first ever purchase also in 2015.
I thought about buying a top of the line Sc type but instead chose to by a basic Sea Doo in the GTI-130 , learn about the sport and trade it in later if I see the need to upgrade .
After getting my pwc ,I went looking for Sea Doo information ( should have done that before buying ) and except for Green Hulk web sight that's in BRP's pocket , I learned many things I wish I new prior to my purchase .
It turned out for starters the KISS ( keep is simple stupid ) paid off big time for me after discovering the somewhat unrepairable problem with Sea DOO's SC and the need to pay around $900 per unit every 100 hrs ( not 200 like BRP's sales staff had put into the manual to boost sales ) ,So if you keep both for a 1000 hrs , your looking a 18 grand and I guess you can see I thank God I dodged that bullet . If you do a search you will find their SC have been involved in class action law suits . Everything else about Sea doos in general are 1st rate including the engine your sc is bolted to its just the sc .I just past 300hrs on my pwc with no break downs just normal routine stuff ,
In ""2016"" they finally came out with with a totally redesigned , maintenance free sc that in the short run is also encountering problems but on its way to being a good device .
If I was you and the new ACE supercharger can be installed on your 2015 , I would consider buying 2 of them and chucking the defective ( in my thoughts only ) part keeping in mind that a sc failure can totally destroy your engine .Of coarse if you wait awhile the courts may make fix the defect for free as has been done in the past if your fortunate .
I suggest you take the time to learn about the new Sea Doo, ACE maintenance free SC on this site and by doing a search .
Another issue that comes to mind involves the plastic muffler we both have .
If the exhaust tempt warning beep comes on be sure to shut the engine down right away .
The only time I have ever herd the beep is when I tried for only about 10s to run the motor on the trailer after use at the dock to empty it of water so I don't do that anymore .
High exhaust tempt can melt the plastic muffler we have , water will come in and can sink your boat .
Theirs another class action law suit involving that so hopefully in the near future we might get a free melt free muffler .

Although some may strongly advise against this , I have decided not to flush my exhaust system after each use .
The water my pwc runs in is either brackish or fresh water especially during the last few minutes to the dock .
The engine must be running before you connect the flushing hose .
Then the hose must be removed before you turn off the engine .
Get the order wrong , and you will screw up your engine and it will probably go down as the most costly mistake you will ever make .
I am not sure about how the intercooler fits into this so if you have to flush , please be careful.
When I was flushing , I had it set up so I had to remove a old quick disconnect from the flushing hole before doing it .
This useless , extra step acted to reminded me to start the engine 1st .
