[C38] engine temp

[eyriepg at comcast.net]

About 4 years ago, I notice white "smoke" coming from the exhaust of my Yanmar.  I had the dealer service the engine to the tune of about $300 and went cruising.  I didn't get very far before the engine overheated.  My first thought was to check the raw cooling water supply.   I disconnected the intake line at the strainer and tried to blow through it.   It was completely blocked.  I guess the white smoke was steam created by the heat exchanger.  So I connected my inflatable boat bellows to it and pressed.  It wouldn't press.  Then I sat mightily on the bellows and something gave way and I was able to blow through the hose.  The engine has run cool ever since.
