CARE AND STORAGE

O-rings should be stored in clean plastic bags to protect them from dust when not in use. Avoid prolonged
storage in direct sunlight as this may result in deterioration of the O-ring material. Stored O-rings should be
sorted with regard to type and size with that information noted on the storage bag. Use of an incorrect O-ring
can result in an ineffective seal.
8.3.4

HANDLING SEALED COMPONENTS

O-rings and other components with sealing surfaces should never be handled with dirty or gritty hands. A
small amount of dirt trapped next to an O-ring will cause leakage, which could result in serious damage to the
equipment the O-rings are intended to protect. The most common situation is a single strand of hair or lint, so
care should be taken to ensure a clean work area. Should an O-ring or sealing surface become dirty, wash it
with mild soap and water, and then rinse it with clean water. Avoid scratching the surfaces of O-rings and the
components that contact them. Do not use sharp objects such as a knife or screwdriver to pry apart sealed
assemblies or remove O-rings. Serious damage to the O-ring or the seat may result. When components
require storage with the sealing surfaces exposed, they should be stored in a clean, dry location for protection.

SERVICING THE LIGHTS

8.4.1

REPLACING A LIGHT BULB

CAUTION! The Light Bulb may be very hot.
1) New bulbs should not be handled with bare fingers. Oils and acids from hands and fingers can affect the
bulb and result in shortened operating life. Protect the bulb with paper towel or a clean cloth during
handling.
2) Open the light housing by carefully unscrewing the light dome. Using a clean rag, grasp the light bulb
and pull it from its socket.
3) Insert the replacement bulb and reassemble the light dome, making sure all O-rings are properly installed
and seated.

THRUSTER GUARD AND PROPELLER REMOVAL

8.5.1

THRUSTER GUARDS

To facilitate cleaning, the flotation block may be removed by removing the retaining screw. The port and
starboard thruster guards can be removed by unscrewing them from the thruster pods.
8.5.2

PROPELLER REMOVAL / REPLACEMENT

Important: The vertical thruster uses a propeller design that is different from the horizontal thrusters.
You cannot interchange these propellers. Doing so is likely to cause damage to the thruster motors due to
the different load and power consumption requirements. This damage is not covered under the warranty.
The Pro 3 uses counter-rotating horizontal thrusters. This helps maintain stability. The port propeller has a
reversed pitch from the starboard propeller. The horizontal thruster shafts use a right hand pitch thread, so
it is possible to place the port propeller on the starboard thruster. This will result in reversed operation and
should be avoided. In order to identify the correct propeller for each thruster, note that each shaft rotates
such that the top of the shaft moves towards the main hull when forward thrust is applied. The leading
edge of a propeller blade rotating in this direction must be toward the front. If the leading edge of a
propeller blade rotating in this direction is toward the rear, the propeller is on the wrong shaft.
Use the following steps to remove or replace the propellers:
1) Remove the flotation block by unscrewing the retaining bolt, or the horizontal thruster guard by
unscrewing it from the thruster pod.
