Location: Conn in summers , Ortona FL in winter , with big dock & room for O'nite stop .
6-71 and other engines can eat so much fuel to be worn out.

As a 1200rpm Gen set 30,000 hours is not uncommon .

1800rpm . the daily fuel burn will higher and service life lower.

In a boat that does not attempt to plane , service life is usually extreme.

The fish killers tweak the units to run 450hp with a couple of turbos , 1000 Hours is considered good longevity.And at 60GPH it will eat almost as much fuel as the gensets in its life

How the boat is run will determine the life.
