2001 Murcury 90hp Was Seized
I have 2001 Mercury 90hp it was given to me with the pistons seized... It took 4 week but I got it unseized...I have a couple of issues... one I spun the nut that holds the flywheel down...I believe the threads on the crank is gone as well... when trying to get the motor upsized, I started with a 600 pound impact and ended with a1200 pound impact which in turn spun the nut on the crank. ok first question, can I try a different size nut on the crank, to try to cut new threads on the crank itself, or well I have to tap the threads on the crank... Second question, I got the motor to run on muff's, it runs very well with no issues so far... can I use anything to protect the walls of the pistons, such as some type of oil or piston saver... lol...
Any Help would be appreciated... thanks Mav
