Overload preventing method of fishing boat engine

Abstract

Abstract PURPOSE:To prevent overload of engine during fishing work and to lengthen the service life, by providing an air delivery piping around a propulsion shaft to eject air and removing sea water in the vicinity of screw. CONSTITUTION:Required number of air delivery pipings 3 are arranged around a propulsion shaft 2 while facing with a screw 1 and separated by predetermined distance from the bow side. Then required amount of air of predetermined pressure is ejected to increase the engine rotation thus to regulate the power required for propulsion of vessel against the driving force for hydraulic fishing system, generator, etc. during fishing. Consequently, engine overload can be prevented.
