I agree buddy, because that engine has never been run, I’m sure everything under the hood is in great shape and is ready to use.
Your next decision is a tough one for sure. It is so tempting not to use the engine, perhaps display it, but that is a decision only you can make. Sounds like you have no interest in displaying it, so I’m guessing you will go ahead and use it. Which is great, the engine should be used and appreciated, but I wouldn’t start it up until you are ready to use it. Once the gas/oil runs through the carb/hoses, those items start to deteriorate. I’m sure you can buy a nice sturdy/heavy canvas cover for the cowling to keep it from getting to scratched up while transporting and using. You can use an inexpensive plastic tank, and make up a fuel line with primer bulb and the appropriate merc connector.
Doing the impeller job on this engine is much easier than most of the OMCs, the mercs don’t have a shift rod connector to mess with. So, remove a few bolts with the gear shift in forward, then it will slide right off. It is new, so corrosion/sealer is not an issue. I’m thinking this job could be completed in an hour or so. Once you are ready to do the job, I know someone here can supply pages from the manual and support for you. For now, you should look for an OEM Merc manual to purchase, review it, and ask questions.
