That is definetly excessive. How are you normally running the boat. Do
you do a lot of idling or almost all top end running?

To my knowledge there is no adjustment. Check for line leaks also.

The boat I just bought has a Merc 2000, optimax 225 engine, it seems
to burn too much oil. It seems to use about 3 gallons of oil for
every 80 gallons of gas.. Is there an adjustment or some likely
thing to check.

Thanks,
Jon
