• 

Uncouple the engine tie bar from the outdrive 
tiller arm by bending back the lock tabs and 
removing the cotter pin. This should be 
replaced with the multi-engine adaptor pin, 
ensuring that it is secured properly with a split 
pin* (Fig.28) (on single engine installation, fit 
the single engine adaptor pin in the vacant 
middle hole in the tiller arm). 

• 

Attach the drive unit to the bracket using the 
long cotter pin and split pin provided. The 
small spring clip can then be used to attach 
the drive unit to the adaptor pin (Fig. 28).  

• 

Slowly turn the steering system from hard 
over to hard over. 

It is most important that 

the drive unit and the adaptor pin bracket 
do not touch any part of the engine or 
steering system.
