Genuine Mikuni BN40i Carb Carburetor SeaDoo 717 720 GS GTI GTS Sportster. Removed from 1999 Sea-Doo GS 717 rotax sold as is for parts, or rebuild removed from freshwater ski
I rebuilt my old carb twice with no luck, I was beginning to think I had a different problem. I decided to try a new carb just to be sure. Now it runs smooth and strong, the boat has never been faster. Just buy one you won't regret it.
