Other things are the orientation of the fuel line, the vent on the tank cap, tight battery connections (sounds like it cranks OK but doesn't run?). Failing that, I'd pull a plug and check for fuel being present, then check for spark while cranking. Dave - 1983 Outrage 22

Had that fuse break for no good reason once. Replace fuel filter (don't just look at the bowl) check to ensure fuel is flowing to the engine. Had a buddy put a new fuel filter on his boat last week after changing the filter the boat ran fine. Next day it even ran for about 10 minutes before the filter clogged. We bypassed the filter and boat ran fine. So we changed the filter again and blew out all the passages with air.
