Default Mercruiser 4.3L loses power and surges when hot
After about 30 to 40 minutes of running at 3000RPM, my 86 4.3L 205 HP
Mercruiser starts losing power and when you slow down, it surges heavily and
stalls often. I have a clear gas filter in the line next to the carb and it
is still full of gas. The engine is not overheated.

Any ideas?
