    • Direct Replacement-Works GREAT
Review Image by Carlos Pacheco Carlos Pacheco
The media could not be loaded. I originally had an issue with the first carburetor shipped to me wrapped in plastic. 1st carburetor arrived damaged from shipping, broken & bent fuel nipples. Contacted seller, he sent me label to send back damaged carb and sent me a new one in a box this time without damage. Now that I have installed the new carburetor and tested I’m ready to leave my review. My ski was a 97 Seadoo GTS with the 717 motor. My symptoms were the engine would bog down at top speed every 3 seconds. So it would hit top speed bog down then hit top speed again continuously so it would never stay at top speed. All fuel lines had been replaced, gas tank cleaned the only thing left was the OEM carb on my ski so I figured replacing instead of rebuilding. This carburetor was a direct fit replacement! I took photo of the old carb vs new carb so you can see the difference of how dirty the original one was. I also have a quick video of how the ski turns on immediately with the new carb. Excellent start up & now my ski is running flawless & hits top speed and stays at top speed with no problems. If anything the ski feels a little more torque now that it has a new & clean carburetor. I highly recommend this carb if your ski has the same issues! ... show more

The media could not be loaded. Carb is similar to OEM carb on a 1997 seadoo. Easy to install if you have some carb knowledge. Jet ski started right up after first try.. video of first start up in 8 years

    • Happy.
I own three ski's now and a 5672 Challenger. I've always built with OEM Mikuni Kits but these accelerator pump's are tricky. Anyways, I'll build a carb perfectly, I mean I know what I'm doing and sometimes it just doesn't work. I popped this into the Challenger and it instantly started up after the fuel primed. My package also arrived Five days before it said it would (This last part is subjective maybe I got lucky) Thanks! Will be buying another for the other engine. ... show more

    • Great carb. Delivered broken
Review Image by Andy Harvey Andy Harvey
This is an great oem carburetor replacement just what I needed to get my machine running again without rebuilding the old carburetor after on the machine 15 years. Only problem was when shipped it wasn't packaged very well and the fuel nipple was damaged and cracked off. The vendor is sending a replacement part at N/C so I'm satisfied with that . But it could have been avoided if it was packaged correctly in a foam wrap. Oh well life is full of disappointments but it's an easy fix. I still recommend buying this carburetor of you need it. OEM stamp on the body. ... show more

    • Very pleased
Perfect tune, bolted on and started right up and ran great. No adjustments needed. Wish I’d have bought it a couple seasons sooner.
