I find that mine is always wet, and now and then starts to smell terrible. This is bacterial growth. It can also be...

Re: Yanmar 3GM 30 Cooling Water Mystery

That's not scale, those are bits of old heat exchanger pencil zincs. The zincs frequently corrode through at the base, then break off.

Re: Will a Airmar DST800 transducer fit in a Navman thru hull?

No, I'm afraid they aren't standard. Even if, by some miracle, the DST800 has the right thread AND diameter, the length also has to be spot-on to put the transducer flush with the hull.
