This weather is total crap....:mad:

Anyhow we are supposed go below freezing tonight so I figured I better drain the cooling system on the new boat. The manual is a bit confusing, so I thought I better ask around here.

It's an '08 Merc 4.3 TKS (carb'd). I found a total of 5 Drain plugs, however the manual shows a drain plug for the fuel cooler(?) line and an optional check plug. I can't find either, so I'm thinking the fuel cooler is for fuel injected models and I don't have the optional check plug which looks like it's supposed to be around the water pump somewhere. Anyhow I drained the five plugs and left them off, is there anything else (or missing plug) I should do before tonight?

NM. A quick forum search showed me that someone has already posted 5 as the magic number.
