Re: [OMC-Boats] Oil change math...

Just a note of clarification for OMC 19-ft V8 owners:

The 210 hp Chevy 307 has a 5-quart pan (6-qt with new filter) capacity.

The 200 hp Buick 300 has a 4-quart pan (5-qt with new filter) capacity.

Just be careful not to overfill.

It's always re-check levels overnight after changing oil. It takes
quite awhile for the oil to settle in the pan for a correct reading.
