Comments about Groco Groco Seacocks - Tri-Flange Base:

I installed this seacock and thru hull in my sail boat with little problems. This is a great unit. Sturdy and solid. Much better thah the flimsy plastic units found on many production sailboats. And it's cheaper. I used a 3/4" plywood backing plate between the seacock and the hull with ss bolts imbedded in the plate for mounting the seacock. The thru hull fitting screws right into the seacock sandwiching the hull and backing plate together for a firm water tight installation. It should out last me.

I replaced a 36 year old thru-hull and gate valve set up with a Groco seacock and thru-hull. It is exactly what you would want in a seacock- solid, durable construction. If it installed itself it would be even better, but installation was a snap. I'd recommend taking the time to make a good backer plate. I fixed some brass nuts into a plywood disk with resin, then coated the whole disk to help prevent rot. On the advice of the boatyard, I Sikaflexed it in, rather than glassed it, as eventually the plate will need replacing (many years down the road). You get what you pay for with this product.
