Hi, hoping for some perspective here. I'm putting an offer on a 25 foot inboard fishing boat with a 350 inboard raw water cooled engine. 10 years old, 600 hours.
Oil analysis on engine and gears good, except for 72 level sodium.
the mechanic's survey noted minor corrosion on the manifold/riser gasket but all else checked out ok beyond needing a tune up and oil change.
Am trying to put that 72 level in perspective. Is it an oil additive, or do i believe i'm on the way to a bad gasket or worse a cracked head?
Would appreciate any input.
Thanks!
