Straight Thru-Hull Fitting 1-1/2''

hello
does it matter metal plastic? i need one to use with new tuna tubes having installed on my boat in costa rica .my manager said they cant find that size in costa rica wants me to bring one but didnt say what knid

thanks

 

For tuna tubes, probably what you need are pvc fittings. Since I don't know all the particulars I'm just guessing of course. But for through hull fittings below the water line you definitely want bronze, or stainless at least.

 

i would think its below waterline to suck up the water to run thru tubes right?

 

Most folks I know use the raw water washdown pump to feed the tubes, so that plumbing should allready be there if you have a washdown pump. I assumed you meant the fitting to connect the tube manifold to the washdown pump.
