Mercury 8hp Outboard Stalls.?
Engine starts right up but as soon as fired up slowly runs down and stops. Will prime again and restarts easly but stalls again. Will not continue to run no matter what. Unable to keep running even if increasing throttle. Replaced fuel pump diaphragm with no results. Seems to run down quicker than using up the fuel in the bowl.

remove the side plate and inspect the pistons. sounds like damage. if none, give the carb. a thorough cleaning. check fuel lines, tank, etc., for leaks...air leaks.

Make sure that you put the gasket in right, they can be tricky, and leak air, I'll bet that's it !
