Milky outboard engine oil

[joefishmore]

When  the oil on the dipstick is milky is that a major bad sign ?

i had that in a boat a while back and it all had to be drained.

Yup!
Blown head gasket or cracked head allowing cooling water in there to foam your oil.
Get it checked.

[deerhunter]

macs right. milky oil means water

[stguy]

It's  not a good sign, don't  run it.


It could be as simple as condinsation, could be a bad head gasket, could be a crack somwhere.

It doesn't  take much water to make things look really bad.

Take it to a mechanic, may have to Bust Out Another Thousand or more.

Bust out a 1000 more refers to $$$$$ I guess, Moter is over 20 years old.
How many of you would vote for junking it ?

My cousin recently had a similar situation. A boat and motor they had bought last year with their house started to have some issues running. They also discovered milky oil. They brought it down to a mechanic, who told them since it was about 25 years old that they could pay him to go in, and try to figure out the issue, but he couldn’t guarantee the work or finding the issue. He said in his experience unless you completely tear it down and rebuild it (which is crazy money for an old motor) the first issue he finds/fixes may not be the only one.

They just bought a new motor rather then pay a tech to try and figure it out.

All depends on how many HP. A small one replace,a big one repair.

I (almost) agree.

A big one, have it looked at.

Find out where the water is coming from first.

Did the oil level on the dipstick change?

How many hours on it?

Has it been overheated/water pump impeller failed?

If it has been maintained well it should go a couple thousand hours or more before it turns to junk.

Check the compression in all the cylinders, if the compression is good, drain the oil and flush the crank case with some kerosene or diesel fuel, change the oil filter and put fresh oil in it and run it for a few minutes and see what happens.

If one cylinder is down on compression, chances are it's a blown head gasket and shouldn't be a ton of money to fix.

With the cost of new outboards these days, it would be worth finding out where the water is coming from.

Its a 130 Honda, has had a few other issues, and I guess he is going to try to find somebody to look at it as close to Yarmouth as he can.

[lobsterman]

id get a newer model with EFI that way your not screwing with carb cleaning im sure its and easy fix head gaskets aren't to bad but think about EFI

[stguy]

Just talked to a friend of mine, if you end up looking for a new motor, he has a 2004 honda 130 with 900ish hours on it for sale,  comes with a 1983 23' Grady white attached to it, sitting on a nice trailer, all for 8000 bucks.

Definitely get it looked at before deciding anything!!!! New motors are NOT CHEAP BY ANY MEANS!
