Protection device e.g. propguard, for e.g. propeller at outboard motor, has pipe section, where casing surface in area of cavitation plate is recessed, and ends of surface are firmly clamped with profiles connected with plate by bolts
摘要
<p>The device has a pipe section of arbitrary length, where a casing surface in an area of a cavitation plate of an outboard motor or a similar marine drive is recessed. Ends of the casing surface are firmly clamped with profiles that are connected with the caviation plate by bolts. The pipe section has radius larger than radius of the propellar and the casing surface is open at the top.</p>
