Anyhow, I WILL get the screws out and when I put it back together I will

Thanks,

I spoke to a gentleman who runs an outboard motor shop. Outboards are
typically made of aluminum castings with stainless fasteners. He
recommended to me that I use pipe dope to coat the threads instead of
anti-seize. I used Rectorseal, and the next time I dissasembled my
motor it came apart easily.

Good luck,
Andy
