    An outfit called CaviDyne seems to have the technology for underwater pressure cleaning...

    Looks like a spiral blasting nozzle but hard to tell under water.

    Wouldn’t do the shaft seal much good.
    Can’t be UHP, lance is too short, Heath and Safety specify minimum lance lengths to make it impossible to shoot yourself in the foot with both hands on the gun.

    After looking at Cavidyne,put a rotating nozzle on the gun after cutting it down to just pistol grip size.
    Pushed the pressure up to about 180 bar ( most prob kill the motor now) and gave it a test .Most light fouling is removed easily but barnacle growth still too stubborn ,now thinking to inject a flow of air into the waterjet to assist in the process as it seems cavitation is the key.
