Welcome aboard TF.
Ours is a '08 34 HT
I see David beat me but take a look at the "Bacchus" website for info on 34Ts.
I switched out my wipers to the straight blades w metal backing.
My local NAPA store had the right adapters to match up with the arm ends.
A common weakness on MS 34 salon AC is the duct atrachment or lack of to the pirt side discharge manifold. I found mine was not atrached and had slid down the enclose chase at the port stern. Not easy but I was able to make the connection by working through the stereo speaker hole. It made a huge difference in cooling.
I suspect that if you are getting good cooling now yours is attached.
I see you are from Mt Pleasant.... where is that?
We are in NY Finger Lakes but frequently cruise Lk Ontario, 1,000 Is & Canadian Canals.
