Seems that a seal is gone on the front mount of my sea Star teleflex 1.7 6.9amps 1000psi max.<br />part #Hc5345<br /><br />My 1st question is: Can I replace the seal or do I need to replace the front mount???<br /><br />2nd question: If I have to replace it do I need to put a block under motor so that it doesn't drop when I pull the rod out???<br /><br />Thank you !!!!
