Can anyone tell me about their experience with a Yamaha 4JH4E Diesel? This was the standard engine in a Catalina 42 MK II and several other boats from 2004 to 2006. According to Yamaha. the model was discontinued after a short production run because it could not meet Federal Emissions Standards.

We have the 4JH4E in our boat, new in 2008. It has been a great engine. Starts instantly on the key every time, even after sitting all winter. I maintain it well, changing oil, antifreeze, fuel filters, etc. according to the requirements. Presently have about 900 hours. A friend has the turbo charged version with 3500 hours. Runs great.
However, YMMV
