What is this?

Thanks guys!
The motor is the one in the signature, an "84 Evinrude 150 horse, premixed fuel.
The compression is the same as 2 years ago, 90psi.
What's your opinion of cleaning the carbs and changing oil type and seeing how long it might take to finish off the piston, or do you think it will cause even more damage doing that?

at least remove that head and clean the stuff out so it won't break loose and make the motor loose a cylinder all together. just clean the head and piston top really well then install back with new gasket run till she dies.

I'll plan on doing that, thanks.
I'll put in line with the detrimental repairs list with the other stuff, which is ahead of the regular maintenance stuff and those are ahead of the other projects.
How did that go? God put me on this Earth to complete a certain amount of tasks, at this time I am so far behind that I will never die!

DO NOT RUN till you get that stuff out of the head or it most likely be the end of your motor.

Thanks, I'm doin like Skools and spare said. Well, when the V's turn comes around.
Got 1 truck that needs calipers (might as well do the pads too), another truck that needs front pads and rear shoes (probably ball joints too), a mini-van that the AC clutch coil once in a while blows a fuse (gotta change it and see if that fixes the problem), Daddy's project boat is a couple of weeks from done, I got to wire it.
Not to mention I got to find time for some therapy killing fish or something.
I'm sure I left someone off the list, but you can bet they will let me know!

I noticed in your pics that you are using regular anti-sieze. I've always been told to use the marine version because it doesn't have copper in it. The regular type on stainless bolts going into aluminum heads and blocks cause electrolosis. Thought you could use this info in the future.
