If you have a lot of patience the air pressure might get it out. I would
try to figure a way the you can keep it hooked up from a while. Still does
not seem to be worth the trouble just to avoid buying a 25$ hand oil pump.

I installed one of the drain hoses in place of the oil pan plug. I push it
out the drain hole in the back of the boat and then just let it run out.
But youy do need to be able to reach the bottom of the engine to do that and
on some boats you can't.

Even if the oil is hot? Most sources I've seen recommend changing the
boat oil when warm when doing through the dipstick tube. The reasons
are to ease flow and to get any particles and polutants in suspension.
If it won't siphon, I could keep the air pressure on the PVC port and
push it out. Right?
