Disclaimer
The interceptor units are also steering
equipment and it is the sole responsibility of
the navigator-operator to ensure that, at any
point, any problem that will alter the boat's
course, rising from malfunction of
interceptors, should be dealt immediately by
the operator. At no circumstances, fault of our
interceptor equipment leading to any kind of
accident, creates liability for the
manufacturer.

A good hint is that the closer the units are to the water line, the best the bank control of the boat will be
(Figure 3).
Attention! Please make sure that the pipe
insertion hole is accessible from the engine room
(Figure 2).
Make sure there are no obstructions behind the
drilling area (tanks, fuel lines, cabling) which can
be damaged or prevent the installation (Figure 1).
1. For high speed boats, overtrim may cause unexpectable turn. Improper use of trim tabs, may result to
accident or injury.
2. DO NOT PLACE YOUR FINGERS INSIDE THE INTERCEPTOR, through the front holes (Figure 4).

Required Tools for Installation
If there is a double installation on the boat please
allow a 18 to 20 mm space between them (Figure

Proper interceptor installation in transom
For maximum performance and less drag, install interceptors on the transom so blades deploy vertically.
If transom is not vertical to water plane, correct the angle by using wedges or other means.
Transom
Interceptor
Wrong
If the boat's transom has a significant curvature, it is necessary to create a flat plane for the installation
(acceptable flatness tolerance: 2mm).
Optimal Less performance Correct angle
More drag

For aluminum hulls, it is suggested Isolation Plates between hull and interceptors to be installed. You can
find installation instructions in the Isolation Plates Kit.

Optional: Connecting Interceptors with Earthing Grid of boat
Except periodical replacement of anodes, you can enhance protection of interceptors from electrolytic corrosion by connecting
them to the earthing grid of the boat:
1. Drill through the hull one of the mounting pattern-holes on the transom.
2. Replace one regular self-tapping mounting screw (M6,3x32), with a longer screw (Inox 316, Φ6.3mm) so to run through the
transom wall (use sealant before tightening the screw).
3. Connect the screw with earthing grid of boat.
*Use inox 316 screw M6.3 of appropriate length
to run through the transom (not included in the set)
Apply sealant Sikaflex 291 to the holes

Attention! The anodes replacement, depends on the sea water quality you have dropped anchor. As the
corrosion of an anode looks like a sponge, for more efficient checking you should touch it to feel that its
smooth surface has become porous. We suggest a precautionary monthly inspection and replacement
before anodes mass is worn over 50%.

BT Series Interceptor and Anode Mounting and Coating Instructions
Note 3: When in brackish or fresh water, use Magnesium anodes instead of Zinc (Zinc anodes are pre-
installed and they are appropriate only for sea-water).
Note 2: Mount anode to the interceptor, so the bump of anode fits into the hole of the interceptor.
Then tight the mounting bolt so interceptor and anode be in direct contact. (see Fig. 2a, 2b).
Note 1: You may apply protection coating on interceptor if you'd like so, but:
1. Do not apply coating on anodes
2. Do not apply coating on the area of interceptors which is in contact with anode (see Fig. 1a, 1b, 1c).

1. Place the Moby Drilling Pattern in the desired position (preferably a clean and easy-to-access area near
the steering wheel of the boat, and with max. inclination angle at 80°).
3. Drill the 4 holes according to the provided drilling
pattern with a 10mm bore.
4. Create the central hole with an electric
handsaw.
