I guess that it also should be said that no seacock, Marelon included, should go for any length of time without being opened and closed, or vise versa. The seacock to our engine gets closed, then opened whenever we check our zinc, usually monthly. The other seacock, which drains our holding tank, gets opened, then closed much less often, but several times during the year. Forespar, in their maintenance recommendations, suggests 'exercising' their seacocks periodically, though they don't specify a time frame. *Rudy & Jill Sechez * *BRINEY BUG-a 34' Sail-Assisted Trawler * *Anchoring Consultants-trawlertrainingabc.com* *850-832-7748 * *Dismal Swamp Northbound-Chesapeake* <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

For hard-to-turn seacocks or those in hard-to-reach locations, I really recommend this "seacock helper" https://www.topshelfmarine.com/product/sea-cock-ball-valve-helper/ It greatly reduces colorful language below decks.
