Re: Closing seacocks
Yes, I close them all, except cockpit drains. I only have 5.
When I purchased the boat every seacock was seized open. The PO never closed them.
I took them all apart cleaned and lubricated them; replaced all the hoses and clamps and maintain them that way.
The 1st thing I look for when starting the engine is waterflow.
