I have a 40 hp 1998 outboard motor when you first crank it runs for about 30 seconds then it floods out we unplug the hose it will run, this weekend we went fishing I was in the back I would plug in hose for a couple of seconds then un plug it, then do it again and again to get us back to bank, no water in gas new can, hose this just does not make sense, this happen before they said i had water in tank boat has been in my shop dont know how it could have water this time HELP!!!!
