Well if we want to talk boats now...

Smaller engines like gas 454, 502 and down you suck it out of the dipstick, since you just can't get to the oil pan drain plug. Doesn't seem to affect the life span of these engines in any way. New oil stays clear for a long time, and you usualy get whatever the crank capacity is out.

Now if you want to talk about larger engines most of them have an oil change system built in. Mostly this consists of pumps, usualy they draw off the bottom of the oil pan. Its somewhat automatic, ie you pump the crankcase empty and then pump it full. Filling up an engine that holds 10 gallons of oil a quart at a time is well, not happening.

But anyway I cannot see any negative affect of sucking oil out of the dipstick. I have never run across a negative, doesn't seem to affect engine life.
