6 Gallons of Antifreeze and no sign of stopping... help?

[pgowdy13]

Hey guys,

I'm winterizing my boat for the first time by myself this year. I watched someone do it last year, and I was fairly certain I could replicate the procedure this year... it seems I was wrong.

I've drained both sides of the block and such, fogged the engine, etc. I'm to the step where I'm adding anti-freeze to the boat. The problem is... I've already used 6 freaking gallons. Last year it only took 3, so I'm fairly certain I've done something wrong now. Attached are pictures of where I've been putting the anti-freeze in. I'm detaching the hose from the exhaust manifold on the right, putting the hose up in the air and pouring it in there.

What am I doing wrong? Should I be pouring it someplace else? Have I caused irreparable damage to the boat?

Help!

Where are you dumping antifreeze into? Did you introducing it from the hose prior to the raw water pump? This is the way I do it:

-drain the block
-drain the exhaust manifolds
-disconnect the water hose coming out of the transmission
-stick a funnel in the hose
-start the engine
-dump 2 gallons of rv/marine (pink) antifreeze into the funnel. The engine will suck it up fast.

With this methode, you know your block is safe, you know your exhaust manifolds are safe. The only reason for the antifreeze, is to ensure that any water in the hoses and pumps are replaced or mixed with antifreeze. I've done this since 1998 without issues.

You didn't damage anything. You're supposed to pour antifreeze down each hose to the exhaust manifolds only you didn't stop pouring when you were supposed to. Eventually it leads out the exhaust flaps and onto your driveway. All you've done is wasted a couple of gallons, no big deal.

Also, if you're pouring antifreeze in directly like this then you're supposed to pour it into the block just past the thermostat and heater if you have one.

On pic 1 the front hose on the left side should be going to the raw water pump.
Disconnect it from the pump bend it up as high as it will go insert a funnel and pour in the antifreeze until it comes out the exhaust.

I do it exactly like Nautiquehunter says above and it eventually comes out the exhaust. That being said, it took about 5.5 gallons this year.

Thanks, guys. I got it all figured out. I appreciate all the help.
