Tired of fighting with the steering on your boat?
Let an Admiral put you in command.

HyDrive, Australia’s largest selling hydraulic steering for small boats, offers the finest in smooth, powerful steering, manufactured to a quality and using materials that are designed to last. Large horsepower outboards are handled with comfort and without feedback from engine torque using Admiral for Outboards.

It doesn’t matter whether you have a small boat with a small outboard, or a larger craft with multiple V-8’s, there is a HyDrive Admiral to suit. Everything you need to handle virtually any boat using outboards, inboards, sterndrives or jet units from 4-15 Metres – delivered in a single carton!

An Admiral series steering kit is basically determined by:

1. type of drive ie. outboard, stern drive, inboard motor or jet drive
2. available space to mount the cylinder (dimensions of the engine well area are required)
3. engine’s horsepower

How to choose the unit to suit my boat
Hydraulic boat steering with HyDrive

Each standard Admiral Kit comes in a single carton including the following items:-

  • Admiral Series Model 401 Helm
  • 2 litres HyDrive ULTRA-15 fluid
  • 15 metres (50 ft) high pressure hydraulic tubing**
  • Installation Instructions
  • All fittings to suit
  • Bleeder Kit
  • Cylinder type of your choice

** MERCKIT & VOLVOKIT do not include tubing

Which Admiral Kit will fit my boat?

For outboard motor steering selection, the most important requirement is the amount of room available either side of the outboard motor. Please ensure that the measurement is taken at the narrowest section of your engine well – particularly with tapered wells, as the cylinder tilts down with the motor.

The OBKIT1 using the 211BH cylinder may be the most practical for installation to allow for boarding ladders, ski-ropes, or other obstacles. The Bosun series kits include 411BH cylinders made from anodised aluminium.

Need some help? Complete this Steering Selection Form and we’ll assist you with the right kit to suit your boat and budget.
