It Usually Means Something
I tend to vary between hoping that a potential problem is really no problem at all, and fearing the worst. This year my exhaust has been showing a little smoke or steam. I rationalized that it was just vapor on cool days, or hot exhaust. I also feared that it was oil or fuel and that my 43 year old engine needed serious repair. Last week as I put her at the winter dock, my boat neighbor observed the steam (now seen even at idle). He also asked about the small amount of water coming out. Sure enough, I realized that as the steam increased, the water, which used to splash out, now only sprinkled. The thermostat remained normal. A joint examination of the engine room revealed no obvious answer, but there was water on the sole. A leak for sure. Today I removed the leaking hose, resolved to examine the rest of the sytem and relace any suspect hoses.
