Come back the next day, and finish your oil change.
Just remember, if you have inverted oil filters (with anti-drain back valves), poke a hole in them so they drain into the pan and out the drain tube as well.

That oil with dirt is still in the bearings :) I start mine the same day with fresh oil. I think it's better to have the motor warm when you start it up. And then the new oil flushes out the oil in the bearings. I use new oil on the filter gasket too . Not the old oil. I m kinda weird. You only have to loosen the oil filter

And mine has the drain hoses. It gets all the oil out . vs trying to get it all out with the pump

I have them for all Merc drain pans. 39 bucks shipped to your door. It is best to not leave them hooked to your hull drain plug and better to keep them off the bottom / bilge.

This started about 2001 for Merc as a standard install but for the past 3 years they stopped that and now is an added option. I can go into more detail later why you should tie wrap or clamp it up plus off to the side in plain visual view along with keeping it away from rotating and heat systems.

Keep in mind its a brass female and brass plug at the end of the drain hose. the female portion is not that stout and easily hairline cracked if you torque its drain plug end too tight also as your hull drain plugs hangs down swaying all over place while towing your boat that keeps pulling on the end of the oil drain hose... Also the hull drain plug swaying as you tow your boat, bangs the exterior transom or bottom area of the hull. Just a few of the negs leaving it hooked to the drain plug. Leaving your drain plug in (tighten) all the time 100 % in most cases is not an option unless marina water stored or lake house over the water stored.. There is more as well.
