You donít tell anything about the vessel itself......is it a factory built vessel with only 150 hours on the engine, or is it an older vessel that has been repowered with this engine and collected the 150 hours?
If itís an OEM installation
I would do the basics as listed by SkipperPete and let it go at that. The engine is basically brand new.
But if this is an older boat
that has been repowered with an new engine,I would have an experienced technician look over the entire installation
, particularly from an engine systems perspective. That is, check the exhaust
system for backpressure, for adequate drop to the water lift muffler
, for adequate ďgooseneckĒ height at the outlet. Check the seawater inlet system to the engine, the fuel
system for potential problems, the air inlet system into the engine room, the engine beds and alignment with propshaft,....as well as the basics as mentioned above.
