It’s been a long (& expensive!) 3 months here in Deep River, CT dealing with our engine repairs. Finally … success! Fortunately, the lack of full RPM on our port engine was “only” the turbo charger (it could have been much worse). Unfortunately, there were no new or re-built turbos in-stock anywhere in the country & ours had a hairline crack in the housing, making the re-build of ours more challenging.
Fortunately, Bill suggested removing the intercooler to inspect & clean (for no other reason than it was now somewhat accessible with the turbo removed). He was surprised to find one end of the casting severely corroded internally – a little more & the seal between the cooling water & air intake would have been breached – a fatal end to our engine. Unfortunately, Yanmar only sells the intercooler complete … for $2,000, plus several hours of labor. Oh well, $3,000 vs. $30,000 for a new engine … probably a good deal. Now concerned, we had him remove & inspect the intercooler on the other engine (a bigger job with that turbo in place) – of course, that intercooler was in perfect condition, but better safe than sorry!
Our sea trial was a complete success & we’re back to full RPMs, sounding perfect! To Bill’s credit, even though this was major “surgery” removing & re-installing major engine components with dozens of fittings & piping dealing with exhaust, oil pressure lines, cooling hoses & fuel lines, there was not a single leak, drip or adjustment needed!
We’ll be off cruising for an abbreviated 2-weeks, enjoying local waters including Block Island & Newport, while thoroughly testing our engines.
