Carburetor Conundrum

Hello All,

This is my first post and welcome any and all suggestions. I am very new to looking at the guts of my engine until last year when my dad decided he had enough with this engine. At this point I've almost had enough with it myself. This is my last effort with this boat so please help a brother out and give me a reason to stay on this forum into the future.

This engine is a Mercury 50hp from the early 80's, I could get exact details and a serial if necessary. It has two carbs and 4 spark plugs. (4 cylinder?)

My neighbor claims the issue with the engine is the carbs. I took both out last summer, cleaned them and put on a new gasket set. I ****ed some stuff up in the process, over-tightening and stripping the screw that went to the bowl, and in the process warping the bowl. A bunch of other ****ups have led me to the point where these carbs are almost useless to me.

My neighbor has mentioned to me the possibility of retrofitting newer carbs onto the engine. Is this possible to do?
I'm very over the current carbs that are currently "on the engine".
I believe I've messed them up beyond my capable repair.

If somehow I can get some other carbs on that sucker to make it work, it might save the boat. Again any suggestions or comments help since my knowledge base is very limited. This project has been a hell of a way to begin learning about the internal combustion engine. Thanks in advance for your time.

Welcome to a patience trying hobby,it would be best to post the engine number so the exact age can be figured.
There are two types of carb for the early eighties 50HP .This link will show you the types and this site here is a good place to get your parts and keeps this forum going.http://www.crowleymarine.com/mercury-outboard/275.cfm
If you have stripped the studs unscrew them and see if you can find replacements from an outboard breakers.
Next,I suggest going to top of the page,click on repair manuals and order one.I highly recommend a manual. Then down to Home Depot/Sears/Lowes/hardware and get a torque wrench,saves stripping threads by over tightening,this particular T shirt I have worn myself.
Patience is a virtue,my ever patient wife tells me I have neither,but it is essential that you take your time. It's a good idea to take photos and lay the parts out as the are removed.Last thing off,first thing on and pics to show the order if you drop anything.
When you get around to to your fourth or fifth outboard you'll be doing it with your eyes rolling in your head wondering why your still at this sort of thing:D:D

Look at your buggered up carb for a part number--it's usually in the front of the bowl. Then report back. I might have one.
