When I run the motor with ears and hose it runs good or when I put the foot a barrel of water runs good. When I take it on the St Laurence sea way salt water. As soon as I start pushing the throttle to get some speed it start to choke up no power and stalls. Start it back up and does the same thing? Is it the ground wire or sensor can't find it.
