Atomic Engine Oil Level

[Alan Cosford]

The oil level dip stick in my recently purchased boat (E-29) has a mark for "low" but nothing to indicate "full". I realize that the oil level will vary depending on the angle that the engine is installed at, but has anyone come up with a simple solution to this?

Most of the dipsticks I have seen have the full mark 1 qt. above the low mark. Why don't you get the oil level at the low mark, add 1 qt., and mark the full mark with a file.
