Hi, all. I'm back from the trip. I'll post a synopsis in another thread.
Lionheart's engine got FLOODED with seawater when we had her heeled to port, hard, between West Palm Beach and Daytona Beach in 8' seas and fantastic 25-30 knot winds! I have an announcement to make..... Lionheart had a dripless packing installed this past winter by her owner who didn't want to fool around greasing her perfectly-great-working greased packing gland. It was installed by a local boatyard with 40 years in the business. Why they hooked up the water injection hoses not required to the engine's waterlines is a mystery to me. It's not required under 12 knots in sailboats. But they did...... A fitting for this purpose was installed with 1/2" hose directly from the water line coming out of the Perkins 4-108 to the fitting on the dripless. Mistake NUMBER ONE. Our heeling hard to port exposed what has been going on since its installation. Water BACKS UP through this hose into the water lines coming out of the engine to the waterline's anti-siphon break in the exhaust system, filling the lines, exhaust waterbox muffler, and the lower-than-the-waterline engine's exhaust system, backing up into the exhaust loop until it eventually, slowly levels itself with the seawater level outside the boat. The whole thing is OVERFLOWING with seawater. If we took the exhaust hose off the waterbox muffler, water trickled out, continuously, into the bilge. The Perkins suffered massive flooding of 3 of her 4 cylinders somewhere between West Palm Beach and the treacherous Ponce De Leon Inlet at Titusville. It was completely hydrolocked. We called Towboat/US who dispatched a 200hp Johnson outboard towboat, immediately. But, alas, the ripping current coming OUT of Ponce coupled with the waves of this East wind at 25-30 made it impossible to tow us. We had to sail into the inlet on our own. Mindwracking is a good term...but we made it. Towed to Daytona Marina and Boatyard, who recommended Cutter Doc owned by J.R., we waited at their quay and he showed up quickly to pickle the Perkins with his mysterious mixture of Marvel Mystery Oil and other mineral oils and water absorbers. Have you seen pictures of the Exxon Valdez oil spill? That's what we pumped out of the Perkins crankcase....sea water and tar balls. Blackened diesel oil, by the way, never looks "milky" with water in it. It looks NORMAL. After pickling and pumping and pickling and pumping he got the crap out of the engine and did a "few" oil changes. The pickling mixture was left in the engine for several days to work off the crud. A final engine oil change and 2 new injectors, cleaning out 2 other injectors and replacing one cracked injector hold down that broke during the starting process and she run like a clock. If you're thinking about replacing your Perkins with some Jap engine....think about what was done to this one and it SURVIVED UNSCATHED. It now runs as new, again....no bent rods, broken cranks, etc. JR's initial idea was that we topped the loop, which in Lionheart goes WAY above the waterline. I was skeptical. The exhaust comes out underwater just sitting level and we put this outlet straight down with the loop tilted 30-35 degrees heeled over....but that wasn't it. After the mechanic left, I kept watching that damned water trickle for days out of the muffler box with the exhaust hose removed. Drove me crazy! Where's it coming from? I took the hose off the seacock and that valve was sealing perfectly. Then I got to thinking about "recent modifications", the new bearing. I took a visegrip and pinched off that hose to the bearing and the trickling stopped......no more water running into the submerged engine. I told the mechanic what I'd found and we agreed that was "it", cancelling the expensive haulout, new holes in the hull for exhaust outlet and leaving the underwater hole capped to flood the hull later....yecch. I probably saved my captain $2K? He sure was a happy camper when I told him about it back in Atlanta....(c; WARNING - If you have a dripless bearing that has a water injection hose that is only needed to blow the bubble out of the bearing when you've had the boat out of the water....PUT A SHUTOFF VALVE IN THE HOSE TO STOP FLOODING THE EXHAUST IN BETWEEN HAULOUTS!! Just thought you'd all like to know....(c; Larry....back online and the Pickled Perkins 4-108 runs like a clock on her new injectors! Thank you to the Perkins engineers who overdesigned her. |
