Bolt on installation of the stern tunnel

1.  Make sure that there are enough space both inside and out-

side the transom of the boat.

2.  Once the place for the installation has been decided, hold the 

tunnel in place in the horizontal position and mark the bolt 

holes. Remove the tunnel and it is then possible to calculate 

and mark the centre.

3.  It is important that the tunnel flange sits flush on the transom. 

If this is not so, then the area on the transom will have to be 

flattened to ensure a snug fit.   

  PS ! Take care with grinders as it is very easy to remove to 

much in fibreglass

At this time, cut out the centre hole and the transom to the 

same internal diameter as the tunnel flange and drill the bolt 

holes. Before bolting on the stern tunnel, the prepared area 

must be sealed with a gelcoat or similar to ensure there is no 

water ingress into the hull. 

4.  Before fitting the tunnel to the transom, fit the lower gear leg 

to the tunnel as described on page 6.  We recommend that 

you fit the oil feed pipe also before the tunnel is bolted to the 

transom.

5.  When fitting the tunnel, ensure that there is ample sealant 

(Sikaflex or similar) in the sealing tracks of the tunnel flange 

and around the bolts to make a water tight fitting (Fig. 1/2).

  Bolts, washers and nuts are not included as they will wary de-

pending on the transom thickness  We recommend A4 stain-

less with A4 lock nuts and A4 washers of a large diameter on 

both outside and inside.  

  Bolts diameter: ø 10mm  or  3/8” stainless steel

6.  Refer to the installation manual for the recommended thruster 

fitting.

If a bow thruster is also installed, we strongly advice to 

use separate battery banks for the two thrusters to avoid 

extreme voltage drop if both thrusters are to be used at the 

same time. Refer to the thruster manuals for adviced battery 

capacity and cable sizes for each thruster. 

Also ensure that you do not have direct connections of both + 

and - if you have built together controls for both thrusters to 

avoid current leakage between separate battery banks.

If you are installing the standard Sidepower dual joystick 

panel this is already secured.
