• Optional Rear Mount (Helm) Kit - Adding his unit means the steering wheel/helm does not protrude into the helmsman's space so much as part of the helm mechanism can be recessed behind the dash. It  fits any model 401,402 and 501 helm unit - adjustable from low-profile to full protrusion for maximum flexibility in helm placement. Simply trim the spacers and studs to adjust the amount of penetration into the helm position. The front dash or console ring is fully O-ring sealed against pump body to prevent water ingress to the rear of the console. Easy to fit - easy to adjust - looks great. (REAR MOUNT KIT)

• Inboard Rudders and Jet Unit Options
  Selection of steering for inboard rudders is not as simple as for outboard or sterndrive powered vessels. Each rudder design has it’s own characteristics which are affected by vessel speed, propeller diameter/pitch, horsepower, tunnels, nozzles etc and this makes selection a matter of calculation, rather than selecting one model to suit all. There is a questionnaire available from Hydrive's Australian website (or your dealer) which, when completed gives all information required to calculate the rudder torques on your vessel. Keep in mind that there is no single formula which can take all types of vessel into account.. We need more information than simply the rudder dimensions, to give you peace of mind that the unit recommended will perform safely and correctly.

• Autopilot Options: - Admiral Series helm units are designed for use with hydraulic autopilots, and have in-built lock valves and balance-line ports to ensure simple and economic installation. The HD Series helm units are also designed for use with hydraulic autopilots and require the fitting of external lock valves (Part No 331C or 318C) to isolate the helm from the pilot pump unit.
