These engines are marketed for use in small fishing trawlers. They put 
out 300 HP each. The same size gas engine can be made to put out over 
1000 HP. The Mercury Diesel engines do not have the problems and are 
much cheaper to maintain.

You do not want to deal directly with Yanmar. They do not honor their 
warranties. The engines in question were well within the warranty hours. 
They are specked to last about eight times as many hours as the gas engines.

I would want someone like Deer to stand behind any Yanmar product that I 
purchased. I would never consider relaying on Yanmar to stand behind 
their product.
