Installation Procedure for A/R Planes 

Tools required:

A/R Planes require these items to install them on an outdrive

¼ inch drill bit & drill motor

Carpenters Bubble level

5/32 Allen wrench

2 "C" clamps

Anti-Seize compound

 

Setup Instructions

1 Remove Propeller (not necessary on some drives)

Instructions for Leveling the Mercruiser Bravo Drive with a level before installing A/R Planes.

   
   
2 Use the Bubble Level on the Large  Anti-Ventilation plate (above the Prop) and adjust the trim until it is level. It may be easier to use the tongue jack on the trailer to get a finer adjustment. (See Figure 1)

3 Position the Port side A/R Plane (the one with ¼ inch holes) fore and aft on the skeg, so that the angles on the front and the rear, match the ends and bottom of the skeg Instructions say to level the A/R Planes on the Mercruiser Bravo Drive
 
 
   
   
   
4 Hold the Level along the top of the surface of the A/R Plane and once it is level, use the "C" clamps to hold it in position. Use masking tape on the ends of the "C" clamp to avoid scratching the A/R Plane.  (See Figure 2)

5 Using the A/R Plane as a drill jig, drill holes in the skeg with the ¼ inch drill. (See Figure 3) Instructions say to drill a 1/4 inch hole in the Mercruiser Bravo Outdrive to mount the A/R Planes
 
   
   
   
   
   
6 Remove the "C" Clamps, and any burrs from the skeg.

    Use Anti-Seize on the threads of the bolts when mounting your A/R Planes on the drive
 
 
 
 
 
7 Use only Anti-Seize compound on the threads of  the Bolts, (See Figure 4)

8 Install the A/R Planes using the bolts in the center first. It is easiest to start all of the bolts before tightening any of them. Tighten from the Center outward until the A/R Planes are flush with skeg surface.  Not Much Torque is needed to keep the A/R Planes bolted securely to a Mercruiser Bravo or other outdrive.
 
 
 
   
 
 
 

DO NOT OVERTIGHTEN BOLTS.  (Figure 5)
