We are talking a 1989 boat here correct?
2 plugs on each side of mine, one on the bottom of the exhaust manifold and one on the block . Total of 4 plugs.
Where is the 5th plug?

It's been decades since I did this stuff. Isn't there one on the bottom of the water pump?
Using antifreeze is a relatively new idea to me. Maybe 20 years ago my marina started putting AF into the block and then reinstalling the drain plugs. The idea was that everything was all set for the winter, and in the spring there was no need to pay/hire a mechanic to reinstall the plugs. Just connect the battery, start and go. The cost of AF was cheaper than the second hour for the mechanic, and the spring scheduling was quicker.
