    ENGINE KEEPERS
    FOR YAMAHA SUPER JET (ALL)
  • Designed in conjunction with (and required by) Blowsion SXR Pro
  • Freerider Air Darin Anderson and SL rider Joe Kenney; these “Kenney Keepers” are a must have for any
    hardcore surf or flat-water invert artist riding a Yamaha Super Jet
  • Each set contains a left and right side front mount retainer and extended stainless hardware for installation
  • Unique close tolerance design retains the front “top heavy” weight of the engine block from being flexed or
  • thrown forward during flat out maneuvers or inverts
  • Since this is a common occurrence even in flat water racing action, Blowsion designers also found them to
  • be excellent insurance against ever having to replace those expensive engine mounts again
  • Anodized blue; kit includes left and right contoured brackets and stainless mounting bolts
