just went down to start the boat after it died on me yesterday. The boat used to start fine but starve for gas as it was always spilling out one of the carbs. pump the bulb and it ran fine stop pumping and it would die. This morning it would not start at all. seems like it is not getting any gas even when choked.
sounds like fuel pump problems if you had to pump bulb,
if fuel runs out of carbs when you pump primer bulb or when running you have a problem with the float hung up, bad float, or not adjusted properly
or bad needle and seat, trash in between needle and seat.
Hope you have a manual to help you adjust everything when you reinstall carbs
