Radio box in place. 

 

 

Lawless drive mounted to transom. 

 

Lawless drilling pattern from manual. 

Seal the inside and outside of the radio box with 
finishing resin or West Systems. Use a metal acid 
brush, bent over, to seal the underside of the top. 
 
Be careful not to get any excess resin in the “lip” 
where the lid seats, as this would interfere with the 
seal of the lid. 
 
Flip the box over, onto some waxed paper, and seal 
the bottom. Allow to cure overnight. 
 
While you have epoxy mixed, seal the radio box lid 
the same way. Do both sides, as well as the edges 
and lay it on waxed paper to cure. 
 
 

Engine Mounting 

If using the Lawless “G” drive follow the directions 
below. 
 
 
 
If not using the Lawless drive, install your drive so 
that when adjusted all the way down, your drive is 
even with, or slightly below the sponson bottoms 
when the drive is level. 
 

 

 

 

 

 
 
 
 
 
 
Locate and cut out the paper template from the 
manual. 
 
Use a little spray adhesive or rubber cement to 
lightly hold it in place on the transom.
