Thru Hull sizes

[cjfj]

I know I've read this on here before but can't seem to find it anywhere.
Does anyone know the sizes of the thru hull fittings on a H34 '83?

I'm planning out my Annapolis buy spree for this weekend:dance:

Don't know if this will help but I just replaced all the thru-hulls and added seacocks throughout on my '86 Legend 40. As follows:

Head overboard discharge (both), galley sink drain - 1 1/2"
Lav sink drain (both) - 1 1/4"
Raw water intake - 1"
Head intake (both), A/C intake, Seawater foot pump intake - 3/4"

If yours came originally (or has been modified) with proper seacocks and you are replacing/repairing/refurbishing, or just replacing the thru-hulls only, no problem. If yours (like mine) came originally with PVC ball valves and you are replacing/reusing them, again no problem. If you want to put seacocks in, beware that Hunter drilled the holes in the hull to accomodate the ball valves and there is not enough spacing between some of the thru-hulls for the seacocks. I had to use a mix of bronze and marlon and stagger them to make all fit (I really didn't feel like relocating all those holes int he hull!)

I have before/wip/finished pics if you want to see what I went through to do this.

I had the Maryland Marina replace all 5 of my through-hulls this Spring. I bought the boat last November and found the through-hulls had gate valves on them. A through-hull and ball-valve was about $200, installed. The raw water engine intake is 1/2". I increased the size to 3/4" when replaced.
The lavatory is 1 1/4". The waste overboard and galley sink drain are 1 1/2". The toliet raw water intake is 3/4", if I remember correctly.
Thanks Guillaume.

I am changing mine currently, here's what I got:

Galley sink 1 1/2
Head outlet 1 1/2
Head sink 1.25
Head inlet 3/4
Spare by the head in/out 3/4 (not sure if this one is original)
Engine 1/2

I am changing the engine thru-hull for 3/4.

Annoying thing is I ordered bronze valves and I received cheap brass ones... Anyone got a good source for bronze valves or seacocks at reasonable pricing?

The Maryland Marina (410-335-8722, marylandmarina.net) has been good to me with parts and service at an excellent price.
