I have 3 used 10ft aluminum carlisle oar shafts. They were originally yellow but the previous owner wrapped them in black duct tape. The tape is dried and starting to peel off, it's not leaving sticky residue, and the yellow plastic underneath looks un-cracked where it is now exposed.
All three shafts are true and unbent. and all three come with sleeves ($15 value). These served me well for a season but now I've upgraded to cataract.
Shafts are approx 7.5ft, 10ft when combined with blades, blades not included.
These are $100/each new plus the $15 sleeve.
$140 for all 3.
