MerCruiser D 3.0 L drain plugs location

[Salomon81]

Hello,

Looked for some information in the internet and found this nice looking useful forum. Searched it but cant find info about drain holes for my Mercruiser D 3.0 L (150HP) motor. Maybe someone can help me with that? I found two plugs, one on right and one left side of motor, but these plugs is too high, I think. There must be more somewhere lower, am I right?

Also it would be great to get info about winterizing this engine. Cant undarstand how to fill antifreeze in the see water cooling system to ensure not freeze the block.

Any information will be useful.
Thanks in advance.

Welcome and nice boat.
As Bt Doctur said, a serial number of the motor will help get you answers.

Re: MerCruiser D 3.0 L drain plugs location

I found on the engine:Type
D183 turbo ac diesel 3.0
is it enought?

And also have one more question, does it has termostat in cooling system and where it is...? I must remove it before filling cooling system with antifreeze.

whats your native language? Most diesels use fresh water cooling and a heat exchanger. The water leaving the heat exchanger cools the exaust. Most times thru a exaust riser/elbow.

Re: MerCruiser D 3.0 L drain plugs location

Thanks for the link. But I cant see drain plugs in these drawings. And what about termostat? If it is, it must be somewhere before cooling block (where see water cools closed cooling system's little tubes with antifreeze, think you call it heat exchanger)? Hope I'm writing clear anought...
Thats right, see water leaves thru exaust. Closed cooling system is filled with antifreeze.

I desided fill up see water system with antifreeze frew see water filter cup. Is it good idea? But if I dont remove termostat (if it is) I cant fill up a whole system, right?

By the way, I found out serial: D0335908

This is my first boat, so sorry guys for maybe stupid questions.


Native language lithuanian, why asking? Very bad english?
We have cold winters, sometimes -25C*, so I must be sure that I will not freeze my engine.

Hi there, is your stern drive a bravo drive?

The serial number is not coming up in the computer system makes this a bit harder to find accurate information for you if possible.

The Mercruiser service manual you need is part number 90-806934 or known as service manual #21 that is not available online. But it looks like you can download it here for $10.00. http://mercruiser.backupmanuals.com/Mercury-MerCruiser-Service-Manual-Number-21.html

Or search the part number for a deal online.

Here is your correct parts catalog for this engine, http://www.mercruiserparts.com/selectDocs.asp?doc_nbr=808742+94

Re: MerCruiser D 3.0 L drain plugs location

Thanks for direct link.

So termostat is in closed cooling system, right? And it is not necesary to remove it, couse there are antifreeze in closed system anyway?

Cant undarstand this part...

Re: MerCruiser D 3.0 L drain plugs location

Jų klausia kokio tipo outdrive tai, kas hanginf išjungti trancą valtis. Bravo outdrives yra stipresnis nei tipiškas alfa automobiliu šioje nuorodoje parodytas jų
http://mercstuff.com/Fiche.htm
Kad therm valdo variklio temp, neturi nieko bendro su šilumokaičiu.Jie laikyti variklio pastovios temp.



Their asking what type of outdrive .what hangin off the transom of the boat. Bravo outdrives are stronger than the typical Alpha drive This link shows them
Sterndrive Exploded Views : MerCstuff.Com
The therm controls the temp of the motor, has nothing to do with a heat exchanger.They keep the engine at a constant temp .

Re: MerCruiser D 3.0 L drain plugs location

I undarstand what for is termostat, I'm just asking is he in the closed cooling system or in open. Couse if it is in closed system it is not necesary to remove it before winterizing (filling antifreeze in see water system).

Sorry, but no idea what you are talking about: Their asking what type of outdrive .what hangin off the transom of the boat. Bravo outdrives are stronger than the typical Alpha drive
What is outdrive...? Maybe you can call it in other word? Something with steering, no?

Hi there, Have a look to see if this link helps you understand what an stern drive is. Sometimes it's called an I/O. Inboard/Outboard.

Well like any closed cooling system you have two parts of the cooling system. You have the sea water side that runs throughout certain parts of the cooling system to help keep the antifreeze side of the system cool.

Since there is two sides to the cooling system, it is important to find and drain the sea water side of the system as that is normal water from the body of water you boat in.

The antifreeze side of the system should not need to be drained for winterization. But keep in mind that the antifreeze does have a service life and should be changed out as a preventive maintenance as recommended in the Mercruiser service manual #21 that if your going to be doing your own service work of any kind, you really should order one up to have it on hand to help guide you through the process of all work being done.

Especially something of this magnitude of winterizing your expensive engine. And since it is a diesel engine, that makes it a bit more complicated for some of us to help guide you over the internet with things like exactly how and where to drain the sea water side of the system.

The service manual should be able to walk you through it better then we can since you would be able to see photos of what you need to do along with detailed instructions of what to do so you don't miss anything important and have a problem next year.

That said, looking through your parts catalog, I see one section that appears to be a drain for your exhaust manifold and with out any experience of this system on my part, I can only guess that item number 9 in the next link below would be for the sea water side of the cooling system.

Please do yourself a favor and order a service manual. Good luck.
