Locate a flat surface (4 " wide x 5" high) where the ladder will not interfere with the turning of the motor or be excessively close to the propeller of your boat. Make sure that the location will be a minimum of 4" ABOVE the waterline at the bottom of the faceplate/assembly and in an area where there are NO electrical wires, hydraulic hoses, water hoses or steering cables.; Check to see that the transom area is sufficiently strong enough to support the ladder while it is in use. If necessary, a backing plate may need to be installed to reinforce the area.; ; Drill a 3" diameter hole in the transom, making sure it is parallel to the waterline.; Place the ladder assembly into the hole and mark the four faceplate mounting hole's locations.; Drill the holes for appropriate 5/16" diameter hardware (not included).; NOTE: It is preferred to through-bolt the assembly for a secure installation (use locknuts and backing washers); ; Caulk the entire area to be mounted and insert the ladder. Secure in place with the selected mounting hardware.; Secure the far end of the ladder to the boat with a strap or some other means to keep the ladder tube in place (not provided as all installations may vary).; Maintenance: Regular fresh water rinsing and periodic cleaning with a mild abrasive cleaner will help retain lustre and help reduce corrosion.; Periodically check mounting hardware and re-tighten (due to normal boat operation).; Safety: Never operate your boat with the ladder in "down" position. Serious injury or damage to your boat or ladder may result.; Information sourced from the Garelick 19700 Series Invisible LadderInstallation Instructions
