Steering Installation
Refer to drawing: HJ21206000 Steering Assembly.
Good steering is of very important on high speed jet boats. This jet, with a steerable nozzle, has a particularly
powerful and positive steering effect.
The steering system on the HJ-212 jet unit is balanced so that power assisted steering is not necessary.
Steering Wheel Number of Turns
Steering is normally operated from the helm by a steering wheel, although a tiller is sometimes used. The
wheel should have between a half and one turn lock to lock for rapid precise control, ¾ turn lock to lock is
normal.
A greater number of turns will reduce the steering sensitivity during low speed manoeuvring.
Most wheel and cable systems are designed for long cable strokes and about 3 turns lock to lock. By
connecting to the bottom hole in the tiller arm [1], this can be reduced to less than 1 turn from lock to lock.
This means that only part of the available stroke of the steering system is used. With excess stroke available,
it is important that tiller stops are fitted to protect the nozzle from over-travel loads.
Tiller Stop Fitting and Adjustment
Refer to drawing: HJ21206000 Steering Assembly.
All water seal faces must be clean and free of grease.
Failure to fit the tiller stops will void the warranty on steering components damaged by
overloading.
From inside the vessel, remove the top 2 or 3 nuts [4], (dependent on whether the jet is fitted on or off the
vessel centreline), spring washers [5] and flat washers [6] securing the transom plate [1] to the transom.


Do not remove the screws [9].

From inside the vessel fit the tiller stop [23] over the protruding screws [9].

Fit the special washer [24], spring washer [5] and nut [4] to the protruding screw [9].

Connect the steering cable to the steering tiller.

If the steering cable is connected to the top hole of the steering tiller, it may be necessary to mark and
trim the adjacent stop until it clears the cable, whilst still stopping the steering tiller.
The steering cable must be connected to the front of the steering tiller. If the steering
cable has been connected to the rear of the steering tiller, the steering cable must be
moved to the front and the mounting point packed out to suit.

Prior to adjusting the tiller stop [23], ensure that the screw [18] and nyloc nut [19] securing the steering
tiller [17] to the steering shaft [1] are torqued to 35Nm (26lbf ft).

Adjust the tiller stop to ensure that the clearance between the nozzle and the nozzle housing is the same
in each direction. Tighten the tiller stop securing nuts to 17.5Nm (13lbf ft).
