Transom Installation
On transom installation, mount your transducer as close to the centerline (keel) of the boat as possible. On slower, heavier displacement boats, positioning the transducer farther from the keel is acceptable.
On
On single drive installations, mount the transducer on the side of the boat where the propeller blade is rotating down to minimize cavitation. If feasible, mount the transducer at least 2 inches (50 mm) beyond the swing radius of the propeller. See figure 6.
Note:
Do not mount transducer directly behind any strakes, ribs, intakes or outlets for live wells and engine cooling water, and any protrusion that may cause turbulence or cavitation.
In-Hull Installation
Transducer installation inside a solid fiberglass hull may degrade performance of depth sounder. Therefore, this type of installation is not preferred over
Should the user desire to perform an
1.Fill a thin plastic bag with water and suspend the transducer in the water.
2.Hold the bag against the hull while the boat is moored and underway and check the reading on the instrument. The reading should be relatively constant.
3.The bag may have to be moved around the hull to find the best mounting location. the best location will be close to the centerline , away from any lifting strakes.
To Install:
After determining that the transducer will function inside the hull, construct a water box to be used for installation.
4.Use a PVC pipe with one end threaded and supplied with a screw on cap. The PVC pipe should be 1/4 inch bigger than the bottom face of the transducer.
5.Install the transducer as shown in Figure 7.
6. To receive a proper echo from the bottom, the bottom of the PVC pipe may have to be cut at the deadrise angle of the hull.
