2014 4.3 TKS motor

[roffey]

I have winterized my motor and just looking to see if anyone has the same motor as I. Mine is a 2014 4.3 TKS Mercury. When I look at the manual for my motor it cover numerous motors and cooling systems. I could only find three drain plugs (seacocks) one on each exhaust manifold and one at the bottom of the motor on the water pump. I believe they call this a three point draining system. Can anyone confirm this that has the same motor.

I don't know your motor but there should be some way to drain the bottom of the motor. Most "V" motors will have a drain on each side just above the oil pan.

Raw water cooled or freshwater cooled?

 

[roffey]

Good question, this sort of confuses me. Are raw water and fresh water cooling the same? I think you mean closed cooling system or raw water? I do not have a closed water cooling, it uses lake water so that would be fresh water or raw?

Feel free to straighten me out, LOL.

 

[thumpar]

That would be raw water cooled.

Do you have your engine serial number handy?

Also what manual are you reading? service manual or owners manual?

P.S, We'll be moving your topic down to it's proper location in the Non-Repair I/O and Inboards Discussions not involving troubles or repair sub-forum.

Motor serial number is pnyusb62i314, and manual is owners manual, very confusing as it covers all inboards and not specific to my motor. That's what you get for 35k, LOL

 

[roffey]

That would be raw water cooled.

That's what I thought but I hear people talk about fresh water cooled. I thought you have closed or raw?

 

[Fun Times]

Motor serial number is pnyusb62i314

That doesn't appear to be a mercruiser serial number. The number would look more like this one for example, 1A063240.

sorry that was the hull number. Ill try once more Serial number is 1a657009

Kind of creepy you would be able to get that information from the hull number but it does not have any actual sale data just what the marina was selling it for and its in American funds. That is close to what I did pay for it.

Some pictures would help. The classic 4.3L has two plugs (could be brass hex plugs) into the water jacket on each side of the engine block. If you had closed cooling its possible that knock sensors were screwed into one or more of these holes but with lake water cooling I would not think this to be the case.

My 1996 raw water cooled engine has a knock sensor. If it has or doesn't have a knock sensor depends on the ignition system used not the cooling system.

Check this video out, start from 17:50, see how this guy pull all his five plugs.

But you Engine is new module, so could be diffirent.

It is a bit confusing, through your link, the engine link goes to a 4.3MPI 220 HP engine.
But 4.3 TKS engine should be a 190 HP engine with 2 barrels cab, like this:
http://www.boattrader.com/listing/2014-Mercruiser-4.3l-Tks-190hp-Alpha-Package-100147371

So I think if you can be sure it is a TKS engine, then it should have 5 plugs

Just for clarification purposes, running his engine serial number shows the engine in question to be carbureted. 4.3 CARB - TKS A 1.7R 4.3L ALPHA.

So I think if you can be sure it is a TKS engine, then it should have 5 plugs

Agreed, your model will have 5 plugs like seen in the video.

Here's your parts catalog for you while I have it open.

Kind of cool, I believe Four Winns has something similar.

And manual is owners manual, very confusing as it covers all inboards and not specific to my motor. That's what you get for 35k, LOL

....When you're ready to start shopping for your service manual that's not available online in PDF, your service manual part number is 90-8M0086018.

You guys are the best, Thanks a bunch. This was exactly the information I was looking for.

 

[roffey]

OK, just went out and checked and for sure there is 5, I missed two. I unscrewed them and no water came out,,, but I remember from a similar post to stick a wire in the hole and out poured water. It was the same for both sides. My bay is a little muddy, it's called mud bay LOL. so... my next step is to fill the motor back up with antifreeze? I keep reading here not to as air does not freeze.

once more, thanks I dodged a bullet there. My wife is adamant I take it to a marina, $200 later...

The answer to your antifreeze question is you'll be fine with or without it. Some dealers add it...some don't. If you run your boat in salt or brackish waters, then it's a little more on the recommended side to add it to help protect from quicker rust formation as time goes on.... But again it's not absolutely needed if desired by you or your wife.

Sounds like you are doing fine on you're own now that you have the water drained....especially from the engine block. Just be sure to follow the owners manual with the rest of the process.
