Page 10: Section 2 - Basic Component Installation
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 fabrica- tion and repair of the hull material in question. Proper mechanical bonding of the tunnel to the hull and support of the tunnel must be confirmed and certified with your naval architect. - Page 11 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 12 The "scallop": A few builders have gone to the expense of scalloping out the trailing edge of the tunnel so as to soften or eliminate the corner of the trailing edge of the tunnel. The theory behind this approach is that, if left un- treated, the trailing edge corner will cause turbulence and hull drag.

Page 13: Thruster Installation
Thruster Installation: • The thruster is held in the tunnel by 6 socket head cap screws. The diameter of the screws vary with thruster size and material. Use only screws supplied by American Bow Thruster. A gasket is usually used between the strut (thruster mounting surface) and the inside of the tunnel. - Page 14 Final Thruster Mounting: • Carefully clean the mounting surfaces on the thruster strut and the inside of the tunnel. • Apply RTV silicone to both sides of the gasket. (If a gasket is not being used, coat the thruster mounting surface with an underwater gasket material such as Sikaflex.) •...
- Page 15 Propeller Mounting: • Clean the propeller shaft and the inside of the propeller hub. Fit key into shaft key way and test fit the propeller. Propeller should make up on the shaft cleanly. If propeller does not fit snug and clean, remove propeller and correct problem.
- Page 16 Motor Bell Housing Mounting (Splined Shaft): • The bell housing is designed to slide onto a boss on the pinion shaft seal housing. This aligns the bell housing perfectly with the pinion shaft. The bell housing fastens through the seal housing into the top of the thruster strut.
- Page 17 Hydraulic Motor Mounting (Splined Shaft): • Apply heavy grease to pinion shaft spline and install spline coupling. • Where applicable, install Spline Sizing adapter. • Apply heavy grease to hydraulic motor shaft spline and fit onto bell housing. Note: Bell housing heights vary. Be sure that your bell housing is not too short. There should be .100" - .350"...
- Page 18 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 19 Electrical Component Installation: Thruster Control Station (TCS): Thruster Control Stations (TCS's) should be located at steering stations near main engine throttle and shift controls. A console cutout template and gasket is provided with each TCS. Make the console cutout as shown and drill the four mounting holes.

DO NOT grease threads Hub Adapter Figure 20 WARNING! Improperly installed couplings are a frequent area of trouble with the system. They can cause excessive wear on the coupling and can even cause the attached clutch to break.
- Page 23 CENTAFLEX Alignment Suggestions: • Remove rubber element. • Check for angular misalignment with a small square. Check through 360 degrees. • Maximum allowable misalignment is 1 degree. 1 degree max. 1 DEGREE MAX. • With element removed, measure distance from outside diameter of hub to outside diameter of flange.
- Page 24 Centaflex couplings are always supplied with Centaflex, Lovejoy fasteners that are coated with a special locking compound. Use only these fasteners! These fasteners should be assembled and torqued only once if possible. However, the locking compound on these fasteners is rated for up to three tightenings. Be sure to read the installation notes on Centaflex Couplings (pg.
- Page 25 SPICER Coupling Installation: Where American Bow Thruster supplies clutch, bracket, and SPICER SHORT COUPLED DRIVE LINE coupling: If a Spicer short coupled drive line is used the pump platform may be fastened to the engine stringers. How- ever, the face of the clutch input hub must be parallel with the face of the engine drive shaft pulley! This is very important! See diagram.
- Page 26 Miscellaneous Pump Information: Adapters: Adapters that allow for direct bolt up of the pump coupling to the engine are usually provided. It is important that all fasteners associated with the pump coupling be given close attention. All required fasteners are usually provided by the factory.

Page 27: Reservoir Installation
Reservoir Installation: FILTER HEAD FILLER/BREATHER The reservoir assembly should be SWITCH ASSEMBLY 9.5” CLEARANCE mounted close to, and above the hydraulic pump. Plan reservoir location so that there will be no more than two HEAT EXCHANGER 90 degree elbows in the pump suction hose. Suction hose is large in diameter, is very stiff, and has a very large minimum RETURN PORT bend radius. - Page 28 Directional Control Valve Installation: DANGER! If the pressure line from the pump is accidentally connected to the T port on the DCV instead of the P port there will be no path for oil flow and the relief valve cannot protect the system.
