Turbo's are fine as long as they are low pressure. Replace them at 2500-3000 hours thou to be safe. If one fails, it can take the engine out with it. MAke sure the engine you buy is IDI not DI. For goodness sake, DI in a boat is a disaster waiting to happen. OH, turbos are cheap. (3-400)
Low pressure, would the Yanmar be considered low pressure? I can't find any numbers on turbo pressure..

Who makes a IDI engine? Yanmar, Perkins, and cummins are all direct injection engines... Why is that a disaster? You get the best fuel economy that way.
