Is there anything wrong with just draining the block and calling in good?
Generally I would say thats OK, with the following precautions.
When the engine block is drained, take a small screwdriver and insert it through the drain hole to make sure sand or rust doesn't
stop up the hole while its draining. Even though I do it every year, it is not unusual to find sand blocking the hole before its drained.
That works for the engine block only. Most already know, but there is a drain plug on each side of the engine block and they are not connected.
Both sides must be drained.
If it's a V-Drive, pull the water pump cover to drain it also.
If there are water manifolds (not headers) the water needs to be removed from both sides. Again, they are separate from
the drain holes in the block.
Anything that water runs through can hold water, so trace where the water goes to be sure.
If you have a jet, others can give advice there.
I'm not a proponent of using automotive antifreeze. It will kill wildlife and fish if it gets in the lake or river.
I once saw a guy start his motor while still on the trailer early in the season and the first thing several of us commented on, was the
green stream of anti-freeze coming out the back of the boat going into the lake.
If a game warden had seen it, sh*t would have hit the fan.
