After 2 hours in the water, the propshaft seals are leaking again and am therefor afraid the shaft is not in good shape. At $425 for a new propshaft P/N 4445452 for a Merc 1, S/N 2361794 , I am open to suggestions for renewing the surface of the shaft. Any suggestions???<br /><br />TIA,<br />swabbie
