Abstract:
A coupler mounting structure for vessels in which an impeller driving shaft in the vessel is supported on a midsection of a vessel body by a bearing member and driven by an output shaft of an engine, said coupler mounting structure comprising:a driven side coupler being mounted on a front end of the impeller driving shaft; a drive side coupler being operatively engaged with the driven side coupler for transmitting a driving force from the engine output shaft; and a collar having a diameter larger than a maximum diameter of the impeller driving shaft, said collar being detachably mounted on the impeller driving shaft on a rear side of a mounting portion for the driven side coupler, wherein the driven side coupler is detachably engaged and fixed with respect to the impeller driving shaft by an abutment between the collar and the driven side coupler preventing an axial movement responsive to thrust on the impeller driving shaft, thereby allowing the impeller driving shaft to be pulled out rearwardly of the vessel by removing the driven side coupler and the collar from the impeller driving shaft.
