Hi everyone,<br /><br />I have twin 318 striaght inboards, that have not been tuned up this spring. I just transported the boat from 1 marina to another which was 60 miles away.<br /><br />After docking, I notice that the port engine (which has 200 hours on it) had 1/4 tank left. the starboard engine(which has 1400 hrs on it) had almost between 3/4 - 1/2 left!<br /><br />What would you mechacanics do to correct this problem?<br />Can a simple tune-up make THAT much of a difference?<br /><br />Thnaks,<br />Lou
