Mounting Considerations • The sensor should not be mounted in a location where it might be jarred when launching, hauling, or storing. • The sensor must be mounted where the hull thickness is from 0 to 57 mm (from 0 to 21/4 in.). Installing the Thru-hull Temperature Sensor Before you can mount the sensor in a cored-fiberglass hull, you must prepare the hull (Preparing a Cored-Fiberglass Hull, page 1). 1 From outside the boat, use a 25 mm (1 in.) hole saw to cut through the hull at the mounting location. 2 Clean the area using a mild detergent or weak solvent, such as isopropyl alcohol, to remove any dust and dirt. 3 From outside the boat, thread the cable through the hull, and gently slide the threaded housing into place to check the fit. NOTE: The housing should slip into place easily, with the flange contacting the hull. 4 Remove the housing. 5 Apply marine sealant to the flange, reinsert the housing into the drilled hole, and tighten the nut. 6 After the marine sealant has cured, remove the nut and apply sealant to the inner side of the hull and the housing. 7 Tighten the nut by hand. 8 Allow the sealant to cure. Preparing a Cored-Fiberglass Hull NOTICE If the core of a cored-fiberglass hull is not sealed properly, water may seep into the core and severely damage the boat.

Drilling a Hole in a Cored-Fiberglass Hull 1 From inside the boat, drill a 3 mm (1/8 in.) pilot hole completely through the hull. April 2016 Printed in Taiwan 190-02057-02_0A
