I have a 24' Wellcraft, 1999, cuddy, 250 HP, 5.7L Merc. It appears the water pump went out thus causing impeller to go thus the bearings went and then cracked head. My boat mechanic said that he could get me a Jasper remanufactured engine and install it for about $4,000.00 or I can get the new Merc installed for about $6,000.00. Is it worth paying the extra for Merc? How much does a boat depreciate with the original engine being replaced? I owe about $15,000.00 on it, should I just sell it with a blown engine and move on? Thanks,,Troy
