I have a 95 Yamaha 225 Salt Water Series motor and anytime the boat sits for more then a week orso, when i start the engine i get a high pitched sound that is some sort of warning sensor. I assume its a heat gauge but im really not sure what it is. The engine pumps water just fine and i dont think its really overheating. It normally shuts down on its own but if i restart it a few minutes later and run it normally the sound sensor will shut off and teh boat will run fine. BTW: the analog temperature gauge i have never shows the boat as overheating.<br /><br />any idea what i can check or replace to correct this problem?<br /><br />Thanks Weez
