Are all Pearson design 323 shafts/strut off to starboard ?
Dolce_Vita:
I seem to recall reading somewhere that the offset angle of the prop shaft had little to do with countering any prop walk. It was there solely to allow for installing/removing the shaft from the outside of the boat without running into the skeg. Sea Haven's observations seem to bear this out.
selene:
Edd, as I recall you are correct in that the offset is not to counter prop walk - as you said, the primary purpose is to ease removal of the shaft. That being said, having the offset and the prop both in the same direction will tend to exacerbate any propwalk.
Eibeltje - reverse pushes the arm down - counterclockwise. Forward rotated the gear shaft clockwise. Note that the arm attached to the shaft in my boat faces forwards, as in the photo, taken through the door under the sink - left to the bow, right to the stern.
I hope this helps..I have come down with a cold, and so decided not to go snorkeling today to verify the offset!! What a wimp, eh? But FWIW Selene was originally sold with a Volvo engine.
Sea Haven:
I checked Sea Haven yesterday.
I was INCORRECT!
My A4 powered 323 Shaft is to PORT, not starboard as I thought. I remember now I it was Cockalada II, a diesel 323 I had looked at last January that has it to stbd. That was the one I reported as user NAUTILUS that had that BAD rust stain on the keel. FWIW, she is now owned by Jerry and Wendy and she summers in the same harbor as Sea Haven! Apparently the son of the owner of the Marina which maintains my mooring owns a 323 as well. It's my understanding he is in the process of restoring her. That means there will be no less than three 323'as in my harbor! Mt Sinai Mooring field is 1nm x 1/2nm. Hopefully I'll get them to reach out here.
Finally, I checked my prop, the blades ARE symmetrical, not swept to either side, so the photo is misleading. The cross section of my blade seems to indicate it it installed correctly with the concave side (suction back) facing aft!
Now to find what's robbing power from me!

Alma:
ALMA is Atomic Four powered with a Walter Vee Drive. Her shaft is port of the rudder skeg.
She backs to port. I use the prop walk to my advantage when docking.
I can't imagine motoring a SABRE with their prop shaft exiting the hull way off center.
There's a Running Gear piece in November SAIL Magazine featuring a Pearson 323.
It describes removing the prop and shaft for maintenance.
Weatherhelm:
On "Barefoot" my Pearson 323 #149 the shaft is offset slightly to the port side. this has the original Atomic 4/ Walter v-drive. RH prop I think Ed has hit the nail on the head it seems the A4's were offset to port and the diesel offset to starboard. but then there are the boats that have had things changed around then who knows
Its sort of hard to see in this picture but its the only one I have of the prop
Cheers and stay warm
