VETUS Stern Thruster Extension Kit For Shallow Draft Boats ID 150mm

For the stern thruster to function correctly, it is important that
the propeller is submerged well below the waterline. If this is not
the case, the propeller may suck air into the tunnel, with a
considerable loss of thrust power as a consequence.
However, on some boats this is not really feasible, because the
draft at the stern is too shallow and because the thruster assembly
should never protrude beneath the bottom of the boat. In order to
ensure both tunnel openings are sufficiently below the waterline,
VETUS has developed an extension kit for stern thrusters. This kit
consists of two shells made of GRP, together with all the necessary
stainless steel fastenings.
The kit can be easily retrofitted to existing installations. It
should be used if the transom is fitted with other equipment, which
may prevent unhindered water flow through the tunnel. It is also
ideal for so-called house boats, which in general have a very
shallow draft both at the bow and at the stern.
