My dad and I fish with 92 stratus bass boat with a 150 Evinrude. We are having a issue with fuel delivery. So we run on the port tank just fine pump the primer bulb and in a few pumps it gets hard and runs fine. This past Sunday we were running low in the port tank so we switched to the Starboard
tank pumped the primer bulb and the buld would never get hard the engine would crank, but as soon as we would take off it would die! Any idea why one tank would prime completely fine, but the other tank will not?
