I bought a small 14' fiberglass runabout from the "late 1970's" with a Mercury 50HP on it three years ago. After the first year, it was serviced by a dealer, who said it was in good condition. 18 Months ago, my wife loaned the boat to a friend and he "Hit something" under the water damaging the propellor. Two of the blades were really bent. He said the engine made a "funny noise" coming back in. It has not been run since. My question is about how much work and expense this will be to fix. Is there probably a lot of damage to an old engine or is there a possibility it could be a quick, reasonable priced repair? I know nothing about outboards and am wondering if it is even worth the expense of starting a repair. Is it worth it?
