I have i believe a 2003 or 2004 evinrude 25 horse motor efi with very low hours on it, it idles fine but when you give it throttle it bogs down. After a while of it being bogged like 5 minutes or more it will start to run like normal. I was wondering if anyone could give me some advice what to look at to fix, i was thinking of changing the fuel line and or gas tank but i don't want to buy those and it not fix anything. Thanks in advance!
