2.Construct a platform (wood, steel, or aluminum) of 5–10 mm in thickness referring to the outline drawing at back of this manual. Fasten the platform to the mounting location. Next, position the base so the cable entrance faces the stern direction.

Note: When drilling holes in the platform, be sure they are parallel with the fore and aft line.

3.Using the hex bolts, flat washers and spring washers removed at step 1, fasten

the base to the platform. The torque should be between 19.6-24.5 N• m.

Note: Longer hex bolts (M10X25) are supplied with the installation materials. Use them instead of the hex bolts removed earlier if the mounting platform is very thick.
