Hello all,

Saturday I took my boat out no prob, the following day it would not start. It cranks fine, batteries are fully charged, spark plugs are replaced. I sprayed starter fluid in and it ran for a split second. I removed the hose attaching the pump to the carb and pumped the ball and gas flowed very easily. The water separator is full to the brim. Perhaps the float is stuck or the pumps are bad inside the carb ?? When I remove the screw at the bottom left, no gas flows out. Thanks for help !!

Kill switch unplugged? Can you hear fuel pump run when key is turned on?

Turns out the fuel pump wasn’t running. I hooked it up to the battery then reversed the battery flow and it started to work again. Boat fired right up !
