Introduction
This manual has been created as an aid to understanding WESMAR bow thrusters, and to provide some
helpful tips. Use it only as a guide. Installations
should be performed by a professional boat yard or a
competent marine service yard.
One feature that distinguishes our bow thrusters from
the competition is that all WESMAR drive legs are
stainless steel, and a sacrificial zinc nut is installed
on the propeller shaft to reduce electrolytic corrosion
(Fig. 1).
When you receive your WESMAR bow thruster, you
should find the following equipment:
• Stainless steel bow thruster drive unit
• Electric motor assembly with solenoids
• Stainless steel propeller(s)
• Zinc nut assembly including shaft key and pin
• Mounting flange bolts and washers
• Thruster gasket
• Owner's manual

Bow Thruster Tube
Installation
Depending on hull material, consult a boat yard or
naval architect prior to installation. WESMAR can
supply fiberglass, aluminum or steel tubes.
Note: For fiberglass tunnels, ensure smooth surface
area prior to seating tube gasket and saddle.
BECAUSE STEEL, AND ALUMINUM TUBES
HAVE DIFFERENT INSIDE AND OUTSIDE DIAMETERS, NOTIFY WESMAR IF YOU WILL USE A
NON-FIBERGLASS TUBE.
Figure 2: The bow thruster must fit completely inside
the tunnel.
Due to ID and OD differences in some steel or aluminum tubes, you may have to build up the bow thruster
saddle or have props cut to a particular dimension.
Check prop clearances before installing tunnel.
Tube Location
For best thruster performance, position the thruster according to the following guidelines:
• Position the tube at least one tube diameter below
the surface of the water. At an absolute minimum,
the distance between the top of the tube and the
surface of the water should be 1/2 the tube diameter.
• Make sure that the tube is between 2 and 6 tube diameters long. At these lengths, no part of the bow
thruster should extend outside the tube (Fig. 2).
• Place the tube as far forward as possible while
maintaining proper tube depth and width.
• To determine bow thruster tube length, be sure you
measure across the widest point of the hull at the
installation site.
• Give the tunnel exit a generous radius to ensure
proper water flow (Fig. 3).
Figure 3: The bow thruster tube should have a generous radius where it joins the hull to prevent cavitation.

Hull Fairings (Optional)
Fairings placed around the bow thruster tunnel may
reduce water resistance. Without a fairng, water is
free to hit the aft wall of the thruster tunnel creating
extra drag, noise, and potentially causing the thruster
to rotate inside the tube (Fig. 5A). There are two types
of fairings that can help prevent this from happening.
(A)
1. The best solution is to create a recess in the aft side
of the tunnel so that the inside face of the tunnel is
no longer exposed to incoming water. Frequently,
the recess is angled down to match the shape of the
water flow in this section of the hull (Fig 5B, 6.
(B)
2. Another effective solution is to create a deflector
that sticks out from the hull on the forward side of
the tunnel. The deflector should hide the aft wall
of the tunnel from the incoming water flow (Fig
5C, 7).
Protective bars are sometimes installed to protect the
thruster from debris. These bars should be installed
length-wise on the hull, parallel to the water flow (Fig.
6).

Bow Thruster Installation
When you receive your WESMAR thruster please
confirm the items you received matches the packing
list. Installation can then proceed as follows:
1. Makes sure the tunnel surface is smooth and free
of contamination to allow gaskets to seal properly.
2. Bolt the thruster unit in the tunnel.
3. Install the propellers onto the shafts and ensure
that they are properly centered and able to turn
freely inside the tunnel. The props should turn
easily and not contact or brush against any part of
the tunnel walls. Make sure that the zinc nut is
pinned through the end hole of the shaft prior to
putting zinc on nut.
4. Determine a convenient location where you wish
to place the oil reservoir. It should be placed
above the thruster and care should be taken to keep
the rubber hose from being caught on any other
equipment or sharp edges that could potentially
crimp the hose shut or otherwise damage it. Once
you have determined your mounting location, cut
the rubber tube to the appropriate length and attach
the end to the fitting on the bottom of the reservoir.

90º from vertical.

Installation
Stern Thruster Installation
1. First, ensure that you have sufficient access to the
inside of the transom for the installation procedure. WESMAR recommends that the thruster be
installed at least one tunnel diameter below the
waterline.
2. Using the provided thruster housing as a guide,
drill holes for the through bolts and the single large
diameter hole for the thruster itself (they must be
perpendicular to the transom). Care should also
be taken to ensure that the bolts are drilled in so
that the orientation of the thruster tunnel will be
horizontal and level.
Note: For Fiberglass Tunnel, ensure smooth surface
area prior to seating tube gasket and saddle.
3. Install the thruster unit in the tunnel and attach the
oil feed line for the external reservoir to the assembled thruster and tunnel unit.
4. Apply 3M 5200 Sealant to the mating surface of
the thruster tunnel (Fig. 9).
5. Bolt the thruster unit to the transom, putting the
bolts in from the outside, placing washers on
washers on both surfaces, and using a locking nut
to secure the bolt (Fig. 10, 11).
6. Install the propellers onto the shafts and ensure
that they are properly centered and able to turn
freely inside the tunnel. The props should turn
easily and not contact or brush against any part of
the tunnel walls. Make sure that the zinc nut is
pinned through the end hole of the shaft prior to
putting zinc on nut (Fig. 11).
7. Determine a convenient location where you wish
to place the oil reservoir. It should be placed
somewhat above the thruster and care should be
taken to keep the rubber hose from being caught
on any other equipment or sharp edges that could
potentially crimp the hose shut or otherwise damage it. Once you have determined your mounting
location, cut the rubber tube to the appropriate
length and attach the end to the fitting on the bottom of the reservoir.

Oil Reservoir
An oil reservoir is supplied with V2-10 and larger
thrusters, and is optional on all other models (Fig.12).
The oil fill plug is 1/4-inch NPT (Fig. 13, 14). Located on drive leg, the oil fill plug is provided to allow
installation of an oil reservoir (Fig 15). It also acts as a
visual aid for checking gear oil level in the lower leg.
Install the oil reservoir as far above the thruster leg as
possible. Use a 5 oz. container filled with SAE 90W
gear oil. Fill oil reservoir with gear oil until vessel is
ready to go back into the water.
A customer-supplied gear oil reservoir for models 6and 8-inch V-6 and V-8s series can also be set up for
the thruster. Install the reservoir above the thruster leg
because it is gravity fed. WESMAR can sell above
optional 5 oz. reservoirs.

Flexible Coupling Alignment
The provided shaft couplings have two setscrews in them each. One of these is aligned with the
bore keyway. This setscrew must be tightened down against the key of the given shaft. Align
the coupler halves such that both shafts have setscrews set against their respective keys and that
the coupler halves firmly together about the hytrel insert. If a setscrew cannot be driven into its
appropriate shaft key then the shaft and coupler alignments must be adjusted to correct this (Fig
15, 16).
Note: all setscrews must be tightened down prior to thruster operation.
Figure 15: Improper shaft alignment prevents proper setting of setscrew against shaft key.
