*So. Should you fill to the manufacturere recomended oil level or ammount and adjust the marks on the dip stick to account for the angle of the engine?

Depends on the engine but the Ford Lehman 120 in a typical rearward slant position in a boat should NEVER be filled to the factory-full mark on the dipstick.* That is because doing so will put a fair amount more oil in the sump and the level at the rear of the engine will too high.* The rear oil seal of the Ford engine was not designed to be immersied in oil.* Which it isnt if the engine is mounted level in a truck, tractor, combine, or industrial application which it was designed for.* But it will be if you fill the slanted engine in a boat to the factory full mark.

The proper procedure as outlined in the FL120 manual is to empty the sump of oil, put in the 12 quarts, which is the correct amount for the engine, and mark where this comes on the dipstick.* On our engines, this mark is very close to the lowest mark on the factory dipstick.* Some people put in 10 quarts, mark the dipstick, put in the last two quarts and mark that level on the dipstick.* So you have "full" and "add" marks.
