I have a Sunstream boatlift FL?? about 10-12 years old which I am very happy with. However, I need to renew the spring lines as one line has already worn off and the others need to be replaced.
My question: How do I go about replacing these spring lines.
Thank you in advance for your answer to hd.obab@telia.com and with reference to a manual that shows how to replace these lines
