Size of Thru Hulls E-29

Capt'ns,
Before I remove the gate valves and thru hulls on my E-29 1973 and replace with proper seacocks, does anyone know if they are 1"1/2 or 1"1/4? I bought an 1"1/2 for my E-27(never installed) some time ago only to find out the E-27 was 1"1/4. Of course I realize when I remove the 3 I will know for sure. I just wondered if anyone had done this on the E-29? Would like a heads up. Thanks for your time, Rod

Be carefull of the terminology here. A 1 1/2" thru hull has an outside diameter of the barbed section of 1 1/2" to match the inside diameter of the hose that attaches to it. The inside diameter of the thru hull itself is 1 1/4"

Tim,
Thanks for your reply. I understand what you are saying, others may not. Rod
