Are all Pearson design 323 shafts/strut off to starboard ?

<< < (6/6)

Alma:
After a grounding I had to remove my shaft strut. When I was removing it I found a shim or more accurately an "adapter". It is over an inch thick. At the time I thought it was intended to correct for tolerances in the casting of the struts. Now I believe the adapter is used to offset the strut to port or starboard to compensate for propeller rotation. I can't remember if the strut was completely symmetrical- Maybe it is, and the adapter determines offset.

That knowledge would've come in handy while straightening the strut in a 40 ton press. Instead I had to make a correction then return 100 miles to the boat to match... Tedious at best.

I don't think the offset angle is acute enough to affect the short stern tube. Boats could be manufactured in identical molds and the adapters used to match offset to engine rotation.

Make sense?

If so- The adapter would be simple to cast out of thickened epoxy. THen you could switch the shaft to the other side and solve your problem.

I hope so.
