Well, that's good to hear, BUT....
If it was me, I'd get the appropriate parts and fix it right. With that washer in there, you now have less threads holding it tight in place, and you KNOW that there was some thread damage. How much vibration will it take before it might come loose a bit, and your fuel pump is squirting some gas on that engine while it still runs?? How long before you MIGHT notice it???. There are millions of engines that don't leak when done right.
On a hotrod, when you have a fuel leak, it smells and you can usually tell at the first stoplight (ask me how I know!) ...not so much in a boat, you will not know until it's way too late!
