2001 Mercruiser 4.3 Drain Plugs

[redblur]

This is the first time winterizing this boat, I don't have the owners manual and the service manual I have is no help because it says drain the water.

Are there 4 or five drain plugs on this engine? I've drained the two on the block and the two on the exhaust risers, is that it?

You should also Pull the Big Hose from the engines water curculating Pump,....
And, the P/Steering Cooler,... Either of the Big Hoses here too....
And,.... If it's so equipped,..... drain the Fuel Cooler......
