- Page 4 Section 2 - Basic Component Installation Tunnel Installation: Warning: Thruster tunnel becomes an integral part of the hull. Installation of thruster tunnel should be undertaken only by professionals with certified competency in the fabrication and repair of the hull material in question.
- Page 5 Tunnel/Hull Joint Radius: To minimize inlet turbulence, which can reduce thrust, it is best if the tunnel/hull joint radius be not more or less than 1/10 the tunnel diameter. It is recognized that fabrication of such a radius can be quite time con- suming and expensive.
- Page 6 The "scallop": Some builders have taken the approach of scalloping out the hull at the trailing edge of the tunnel in order to soften or eliminate the tunnel edge. It is reasoned that, left untreated, the trailing edge of the tunnel would cause turbulence and hull drag.
- Page 7 Thruster Mounting: The thruster is secured into the tunnel with six socket head cap screws. Screw diameter and material varies with thruster size and material. Use only the screws supplied by American Bow Thruster. A gasket is usually installed between the top of the thruster strut and the inside surface of the tunnel. Because of tunnel diameter variances, it is acceptable to: (1) use one of the gaskets provided, (2) use two gaskets, or (3) use no gaskets at all.
- Page 8 Propeller Mounting: 1) Clean the propeller shaft and the inside of the propeller hub. Test fit the propeller onto the shaft with the shaft key installed in the keyway. The propeller should make up cleanly on the shaft. If the propeller does not fit snugly, then remove the propeller and correct the problem.
- Page 9 Header Tank Mounting/Lubrication Requirements: Warning! on some systems,the header tank fitting and plumbing must be connected before the driveline or motor are installed, or they cannot be reached. The header tank maintains positive fluid pressure inside the thruster gearbox to prevent water intrusion in the unlikely event of a leak.
- Page 10 Thruster Control Station (TCS) Installation: Thruster Control Stations should be located at steering stations near main engine throttle and shift controls. A console cut-out template and gasket is provided with each unit. Make the console cut-out as shown and drill the four mounting holes.
- Page 11 Installing the Motor Bell Housing: The bell housing is designed to slide onto a boss on the pinion shaft seal housing in order to properly align the bell housing with the thruster pinion shaft. The bell housing fasteners pass through the seal housing and screw into the top of the thruster strut.
- Page 12 Section 4 - Wiring System Power and Control Wiring: System wiring should be installed according to details shown on the System Electrical Wiring Diagram, and on the diagram entitled "Reversing Contactor Assembly: Wire Connections". Warning! Wire sizes must be equal or greater than those shown on the above diagrams. When point to point wire distances exceed 40 ft (i.e.
- Page 13 Section 5 - Miscellaneous pre-start-up notes Corrosion Control: All seagoing vessels must be protected from corrosion from galvanic and electrolytic potential. American Bow Thruster encourages all boat owners to enlist the services of a corrosion control expert to evaluate your vessel's corrosion control system and how your thruster should be made a part of that system.
- Page 14 Section 6 - Final Check Successful Installation Checklist: Did You?..- call American Bow Thruster whenever necessary for answers to your questions? It's important to avoid problems that could require expensive adjustments. - install the tunnel at least 1/2 diameter (and preferably deeper) from the waterline to the top of the tunnel? - have a professional, certified craftsman install the tunnel to the architects standards? - ensure that thruster does not protrude from tunnel?
- Page 15 Section 7 - Operation Preliminary check: • Insure that all mechanical components are properly mounted. • Check that electrical connections are properly routed and properly tightened. • Carefully check that there are no persons near the thruster motor, and no swimmers near the tunnel. •...
- Page 16 Section 8 - System Drawings System drawings included in this section are provided for convenient reference. Before using any of these drawings for any installation purpose, the installer must confirm appropriate matching of drawings to the equipment actually provided. Thruster Assembly Drawings provide important details not found elsewhere in this manual, particularly concerning fastener preparation and fastener seating torque.
