drain the engine

so I failed to do this last year, and paid dearly. Can some briefly explain what needs to be drained so it does not freeze. I've been told the engine and the exhaust, but where do I drain them from. I have an 85 Supra Sunsport w/ F351. Also any suggestions for the batteries. Should they be disconnected or just leave them alone. Thanks.

if you paid dearly for your mistakes... why wouldnt you just go to a dealer and get things done properly?

There are teo drain on the side of the block. On my 351 I removed the brass plugs and replaced them with petcocks. Takes me a few seconds to drain the block now.

The exhaust drains are at the rear of the manifold. Just un screw them and drain.

Its also adviseable to removed the raw water hoes and drain them.

I cant tell you where the plugs are on that engine, but you may have a few as 4 and as many as 6.

The drains may be square or hex plugs, or plastic radiator style petcocks. Should be at least 1 drain in each manifold and at least 1 drain on each side of the block (just above the lip of the oil pan). Need to remove any hoses that may collect water as well like those going through a transmission or cooler, V-drive, raw water pump, engine cooling pump.

When the water is done draining, put everything back together, so next Spring you wont be wondering "why is my bilge pump running and my engine running hot".

My advise, take this down time to learn how to winterize your boat as there is more to it then just draining the block: Oil change, trans fluid, V-drive oil, lube steering, fuel stabilizer in tank, fogging, clean and coat battery terminels and charge up, fuel/water sep filter, new impeller in Spring, etc.

If all else fails, lay a 60W drop light in the engine bay and put it on a timer. This will keep it from freezing til you can get it done. Being in WA, I hope it's not too late, good luck

thanks all!

HeHateMe, I don't have that nice of a boat. And I don't have money. Last year was my first year of boat ownership so I learned a hard lesson. If I take it to a dealer its $120 minimum, not worth it when its just a couple of plugs. and I guess if I'm being honest I'd rather use that $120 for a couple tanks of gas in the boat. so, I heard it was easy, just need a little guidance. ...learning...

You could always befreind a boat mechanic and offer him a case of beer to winterize your boat.
