Excessive Oil Burn with OX66

[Windknotnc]

I took our first offshore trip yesterday on a new to us Parker 23DVCC with 2000 225HP OX66 and burned 62 gallons of fuel but burned an entire remote tank full of oil. That is like 30:1 ratio. The engine runs fine, is responsive, does not have excessive smoke, nor issues idling. Has anyone else experienced this kind of oil burn? Any suggestions besides carrying extra oil?

check for leaks,
and check to make sure linkage is attached and adjusted properly

the yamaha remote tanks come in two sizes, the standard 2.9 gallon and a 5 gallon.
either way thats a lot of oil for 62 gallons.
make absolutly sure of the correct oil link adjustment, or even is the link still attached.
its not uncommon when that engine was new, to have to cut about 5 threads off the rod to get the correct adjustment.
