Don't have a 496 but my last boat had the filter "upside down". Do NOT buy the filter with the anti drain-back gasket inside. After a quart or 2 have drained I simply punch an air hole in the top/center of the filter with a flat head and wait a bit. The oil in the filter runs down out the pan with the rest of the oil. When you remove the filter there are a couple drops of oil to deal with but that's it.

I only buy filters WITH the anti-drain valve. Else, you have a longer dry start period.
I have a "special" screwdriver that is the exact length of the oil filter, NOT long enough to damage the filter housing. It's sharpened to a point, and I pound it in with a small hammer, all then push it all the way through the oil filter.
I usually open the oil drain tubes and poke the filter holes, and leave it overnight. Then come back and fill it the next day.

Do not poke a hole in the oil filter, unsrew it a couple turns just before it leaks oil out. let it sit overnite while you drain the motor oil out the oil drain hose - next day the oil filter will be empty on its own.
Poking a hole in the center of any oil filter runs the risk of the broken metel to drain back into any oil passage. Heard of 2 cases where this has happen and caused engine failures from poking the holes in the oil fitter.
Anyways I already know the replies on this as many will say hogwash " I''ve been poking a hole in the oil filter for years and never had a problem. Can you account for any of the broken metal after you slam a hole into your oil filter ? I'd rather not take the chance.
This alone makes total sense not to poke a hole in the oil filter to help drain it because you do not want a mess but rather have maybe a small piece of oil filter metel drain back in a oil passage or oil hose / line. The center hole of the oil filter is the outlet side after filtering.
Next easy way is you can wrap an oil diaper something like pigmat or 3 m oil absorber towel (in which we use) around the base of the oil filter and finish unscrewing it - barely any mess, just my 2 cents.
