Pilot 30-water in turbo
My 2002 Pilot 30 with a Yanmar 4LHA-STP (1215 hrs) has an OEM turbocharger that just failed due to salt water ingestion. The exhaust elbow/mixer and turbo were original to the boat. During disassembly and bead blasting, the cast aluminum elbow/ mixer developed holes between the wet and dry side and the turbo had so much rust that it was toast. Tony, Seaboard Marine, said that I needed a higher riser to prevent the problem, but there's little to no room between the present mixer and engine hatch. The current system lasted 15 years, so I'll probably just replace the turbo and install a new cast stainless riser/mixer. Has anyone else experienced this problem, and how did you solve it. Also, the OEM turbo is very expensive! I won't use the Chinese copy of the turbo due to the horror stories I've heard. What is the least expensive source for a new IHI (Yanmar) turbo, and has anyone used the investment cast mixers on Ebay? Do the water lift mufflers become restrictive over time, maybe causing water back up to the turbo? I need some help!
