I've recently purchased a new 3.3hp outboard. Compression is 135psi. Will this increase once I begin running the motor? If so likely how much? How low can it be before the motor begins to have trouble?

Irp,<br /><br />I'm surprised it's that high. Especially in a little two stroke. I wouldn't expect it to get higher.<br /><br />Anything over 100 would be OK in my book.
