Hello, newbie here and i have searched through a bunch of threads but cant seem to find what im looking for. I have a 1985 Merc 50hp 4 cyl brown band and after 5-10 minutes of cruising at 1/2 throttle or more it looses power but stays running, idles fine, but sucks the primer ball flat. I have to remove quick connect from tank to get it to re inflate, It does this with the original merc metal tank and a new plastic tank, also the hose and primer ball are also brand new. Any help is greatly appreciated.
