AJ 285

The AJ 285 is the newest jet in the COMBI-FRAME series. The patented Combi-Frame technology allows designers, builders and owners maximum flexibility when locating the position of the propulsion system within the vessel.

Choosing between 2 different hull installation inserts allows the jet to be installed either in LONG TAIL or SHORT TAIL configuration. Following the success of AJ 245 many customers requested the combi-frame installation method for larger, more powerful vessels. AJ 285 is suitable for engines up to 500HP. Applications include workboats, military vessels, pleasure craft and many more.

  • Conical impeller housing
  • Oil lubricated main bearing
