Stern Installation
MC_0036
Stern Thruster Cowls
EN
Installing a stern thruster cowl for stern thrusters that will allow installations in boats with shallow drafts or due to other obstructions on the stern. These
can include obstacles such as trim tabs, jets or surface drive propeller systems where shallow installation of a stern thruster is the only option.
Available models:
Short model:
Designed for maximum thrust for installations in confi ned space, but due to the water being forced to turn rather sharply. (NB: it will reduce the
performance from the optimum standard stern thruster installed at full depth by approx. 15-20%.)
Long model:
Designed for maximum thrust while still allowing a shallow installation.
(NB: it will reduce the performance from the optimum standard stern thruster installed at full depth by approx. 5-10%.)

Cowl water flow redirection
An angled edge further
preventing air attraction into
the tunnel
Composite material with smooth
inner walls for optimal water flow
and strength
A standard Sidepower stern
thruster tunnel with add-on cowls
for shallow installation
cowls to change the
water flow direction to
avoid obstructions on the
stern
cowls help prevent air
from the water surface
entering the tunnel in
shallow installations
Radiused corners prevent
turbulence
Easy installation for easy
