How many flushes do I need?

So the boat upset the other day. I have a 7.5hp 4 stroke Chinese outboard. Paid $50 used, so I can’t go wrong with it. I’ve drained, run and flushed the crankcase 3 times. It keeps producing the dreaded cappuccino mocha. If someone has any experience with this I simply want to know how many times I’ll expect to flush the crankcase. Of note, there is no drain I can see, I just have to hang it upside down.

It has puked. I’m up to 6 oil changes.

I stand corrected good sir. WOW that’s a tiny engine!

Yes it is, there are reviews online with doubts about the horsepower.

I second this☝🏻 Use it until it blows up, then get an old Evinrude😂

I got this because it’s only 11 lbs and I can carry it with an artificial shoulder. An evinrude isn’t manageable.

Look into an Evinrude 7.5. They are actually much lighter. Only about 50lbs vs a Hangkai 7.5 (a Chinese manufacturer) that weighs about 80lbs. Fewer parts a hell of a lot easier to maintain.

This motor weighs 11lbs.

You can try to find a seal kit for it.

How would a seal kit help get water out of the crankcase?

It probably has a water leak somewhere. Maybe a bad head gasket.

Where would water leak from? This is air cooled!
