Yamaha F25A problem

Any ideas,
I have had no previous problems with my Yamaha 25 hp;4 stroke but the other day while returning from a fishing trip (after aprox 40 miutes running time)the engine lost power and started to labour then the warning buzzer sounded,it was turned off immediately and was obviously over heating.I carried on with my auxiliary engine and when back at home some time later restarted the engine which then seemed fine with plenty of water being pumped round the system.
Has anyone any ideas as the cause,as i have lost some confidence with it.

u probably just picked up a bag or some weed around the intakes and overheated the powerhead for a few minutes and went into safe mode . Hey if its running fine @ home on the muffs and pumping water fine then i wouldnt worry too much about it . It a YAMAHA at the end of the day . Dont loose any confindent in it as this happens with all makes of OUTBOARD ENGINES . it probably isnt a bad idea to get it checked out and make sure the impeller and cooling system r all ok . Nothing tooooooooooooooooo worry about
