How to troubleshoot milky crankcase oil on F80?

[andymach23]

The motor is year 2000. I got it used on my new boat in December. I changed the oil at the start of the season and it was milky. I have run about 5 hours so far and the oil is milky again.

How should I start to figure this out? Is a leak down test the best bet for this?

Thanks

Andy

Change your oil first we dont want that water spending any more time in that crank.

Yes do a leakdown test.

Thanks for the reply.

I changed the oil when I discovered it was milky again.
Can a leak down test be done D.I.Y?

Thanks
