I purchased a project s2 9.2a (sat for 3 years) which has a ysb12 engine aboard and as I am new to diesel inboards, I have many basic questions. I have found some info on the web, but I would like some confirmation. I did get the engine to start, but shut it off right away. I have purged all the fuel lines, re primed the system with fresh fuel and it started up quite well. Now my next step is to change the fluids. I am planning on using Rotella T 15w 40 for the engine, but I am unclear as to what fluid goes into the transmission and how much. Also I am unclear as to drain the engine and transmission. I know that I can draw it out from the fill hole, but I am hoping there is a easier way. I have not been able to locate a service manual to download or purchase, if someone has some ideas. Thanks.
