Water in transmission oil

[king474]

I have a 79 invader cc project with what i am guessing is the original engine that is a v8 mercury I/o I bought from a dealer I have the interior all gutted and ready to be redone my problem is when I went to look at the engine now that it's completly exposed I opened up the transmission fill cap and it looks like a milkshake any suggestions or ideas how it could have gotten in there it hasn't been in the water for awile

Howdy,


First of all, what engine do you have, and is it an I/O or do you have a "transmission"? Is it a Velvet Drive?

model number, serial numbers help.


Regards,


Rick

It's a mercury model mcm 260 i/o and can't find a serial number and to be honest my first boat so I can't tell you if it's a velvet drive thanks for the reply need anymore info I'll try my best to get it what I can tell you is that after checking the oil which was fine I looked around it some more and found a cap that said transmission fill unscrewed it and found a short dipstick on it and milky colored oil

Ayuh,...If it's an I/O, it don't have a Transmission...
If it's got a Transmission, it Ain't an I/O...
1st thing you've got to do is properly Identify just What you've got...

First off, it's not a Mercury, that's an outboard, you have a Mercruiser.
Since you have a MCM 260, the MCM indicates is an outdrive model, where MIE would indicate a MIE Mercruiser Inboard Engine. and would have a transmission.
There were also some outdrives that had a transmission inside the boat, but were not used on the 79 model 260 engine, which is a Chevy 350 V8.
So for the moment I would assume you have an outdrive as pictured below. Correct?

If that is the case, and you have the 1 drive as pictured, my guess is what you are looking at is the reservoir for gear lube.
Like this. Is this what you have ????????
