Thru-hull fittings

[Fishinspot]

I'm thinking about changing my thu hull drain fittings out. Which is the best material to use, stainless, bronze, chrome covered bronze, etc? It is a 28 ft center console.

Thanks,

Doug

I'm a firm believer in bronze, but have you given some thought to these?

Southco Stalon T/hulls

Looks of SS at a fraction of the cost. We use them, and have ZERO complaints.

Marelon for me. Not as pretty as chrome but it won't discolor and no worries about corrosion.

Bronze is the most corrosion resistant, If it turns green you can clean it with white vinigar and a soft wire brush and it will look fine.

The Maralon fittings are also pretty good, not sure if they are as safe as bronze, all the boats I work on use bronze below the water line

Marelon is plenty strong. In order to receive NMMA certification we had t apply a 500lb lateral force to the top of a 3/4" seacock. It briefly went over 600lbs while cranking on it and showed no signs of stress afterward. Threw it away anyway but it passed with flying colors.

My 2003 Sea Pro has chrome over bronze thru hulls and they still look new, but mine is not left in the water.

Doug,

What t/hulls do you have in her presently? And are you talking above the waterline, or ALL?

[Fishinspot]

Mine are white plastic, not sure if they are marelon or not. I have several and they are just above the water line. They have never leaked but I don't know how strong they are and I don't want one to pop when I'm 20mi out. There's probably 9 or 10. My under water thru hulls are bronze I think.

This sounds almost like CE cert...
