I am going to look at a boat with a KAD4.3 6cyl volvo/penta diesel. 230Hp with 285 hours...<br /><br />What is the lifespan of this engine? and what should I be looking at as far as upkeep and maintenance on a diesel with that many hours?<br /><br />I am having it surveyed.... just never owned a diesel....<br /><br />Excited that I found one in my area that meets my needs... going to look at it tomorrow
