Drain Plugs on Mercrusier 3.0

[Searay87]

I've searched the sticky's but can't find a manaul or a sketch of my 1987 Mercruiser 3.0L engine showing the location of the drain plugs. This is my first attempt at DIY winterizing. Can anyone help me out?

Thanks,

Bob

There is one on the bottom of the manifold and one on the block under the manifold, both port side, they should either be a brass plug or a petcock
