I recently replaced PTO couplers and drive shafts on both engines and one of the shafts stripped during my second time on the water. I feel the other shaft isn't far behind. Alignment is good and the shafts/couplers were greased on installment. The replaced couplers are from WSM and the replaced shafts are from SBT. I purchased everything through OSDMarine. Before buying another replacement shaft, I want to try and figure out why it was stripped so quickly.
After some research, I found that WSM sells both a 16 7/8" shaft and a 17" shaft, while most other stores only sell a 17" shaft. I'm wondering if WSM's couplers could be a little longer than normal and that's the reason for them selling the 16 7/8" shaft. I called them and they said either length would work with their coupler, but that doesn't seem right.
Any thoughts on what shaft to buy? I'm thinking I should go with the WSM 16 7/8" to go with their coupler. Or any other ideas on what could have caused the replacement shaft to strip so quick?
