Would anyone be able to confirm the size of the thru hulls on a 1988 33 Open. Purchased via broker and doing sea trial in spring.Know one thru hull has a hairline crack and want to replace all when I get it back to my marina. Measured them last week, but now doubting my measurements  : Boat is 2 hours away. 

• Starboard 3 - 1 large 1 1/4? 2 small 1/2?
  
• Port 2 - 1 large 1 1/4? 1 small 1/2?
  

Also the 2 small on starboard are they accessed via the engine area?

Are you asking about the discharge thru-hulls mounted on the hull sides or the bronze intake/seacocks?

1-1/4 sounds about right for engine intakes and 1/2" sounds a little small for A/c or generator. I believe most are 3/4. drop Tiara an email and they will give you the dimensions or part number.

I can’t tell you every size, but when I had my 33, I changed them all out to stainless thru hulls. I removed all of mine, before I ordered the new ones.
