I have a 1993 Johnson outboard on a Ranger 481 VS. I just bought the boat, i'm not sure how long it had been sitting but I took it out the other day and it worked just find. I took it out yesterday, but before I took it out I filled the starboard gas tank and put in a can of sea foam. It stared right up fine but after a little while of fishing I started it back up but when I tried to accelerate, the engine would cut out like it wasn't getting any gas. There is a switch between the driver and passenger seat that allows to transfer between starboard, port and aux gas tanks. I tried switching to the port tank and it worked initially but then did the same thing(the gauge says empty) but it worked every once in awhile. It seemed like when I got it past a certain point then it worked just fine. Any help would be greatly appreciated.
